quants-n-traders

[tranquil wagon]

You said the inverse

[fresh swallow]

The majority of features you get asked about, you will not use in leetcode

[tranquil wagon]

Oh I read it differently

The comma helps lol

Yeah I agree

I didn’t mean Leetcode when I said using them, I meant more like real coding

[zenith panther]

we need to ban these c++ memorizers

fr

c++ is a tool not the trade

😡

[tranquil wagon]

@rose holly wanna see a funny thing

Lmao

We love not making things explicit

[low vault]

Is this just

Casting the object self to

Anything ??????????

[tranquil wagon]

Yes and implicitly too

So it’s even better

[low vault]

We

wtf

[tranquil wagon]

Truly the best language

It compiles and runs

Yeah but when you say it doesn’t actually work it doesn’t tell you it doesn’t work

That definitely is an issue

After creating the monstrosity I actually thought of an example where I’d want that in a codebase

Imagine something like a BitLiteral class that lets you assign a binary value to any object, you could do like

// sizeof(MyClass) == 8
MyClass obj;
obj = BitLiteral(0, 0, 0, 1, 0, 0, 1, 0);

Where the class and constructor have a variadic template parameter and there is a static assert in the cast operator to make sure you are assigning it to an object of the same size

Maybe but this is more concise

Yeah something like that lol, it’s a bit out there but i was just trying to think of any situation where that code snippet would be actually practical

[low vault]

Oh does it not

I figured that it could work on some compilers

Isn’t UB like

“Maybe this could work if you’re lucky comoiler/arch, which is why it’s bad”

[fresh swallow]

Keep in mind this also required making this project one of like, two in the entire repo using c++23

No he wanted me to use it

[low vault]

yeah

old code used to rely on UB though i think

like ppl keep sharing around the quake fastinvsqrt thing

[cedar sparrow]

anyone interviewed for citsec fundamental analyst?

i think i can interview for fundamental instead if want

and its option

and idt i can pass qt process

i’m wondering if fundamental analyst process is easier

[vague forge]

undergraduation 💔

[tranquil wagon]

That’s not UB afaik

Just clever bit manipulation

But it’s deterministic

Carmack definitely did some UB optimizations though like writing out of bounds for scrolling the screen or something

[tranquil wagon]

You mean like you can’t do c style casts of pointers?

Why though

I’ve never run into an issue with doing it

And I do it a lot lol

[low vault]

what about the part where they create a union of a float and u32

and use that to bit manipulate a float

isn't it UB cos the representation is not necessarily well defined

[tranquil wagon]

Oh good point, that makes sense

But in my engine I have a Vec4f class with a method .xyz() that returns a reference to the first three elements which is basically implemented as
Vec3f& Vec4f::xyz()
{
return *((Vec3f*)&x);
}
which lets me do something like
vec4.xyz() += { 0, 1, 1 }
Even though that’s technically UB it works in every major compiler

Thanks, I’ll watch this

Comment on that video that I agree with 100%

[lethal apex]

Not to get extreme or anything but c++ purists should be condemned to the deepest depths of an AWS data center, far away from any ANSI/ISO committee

[tranquil wagon]

Glad u didn’t get extreme

[low vault]

fair enough

I think a lot of these standards were designated back when (CPU) hardware architecture was more of a wild west

and you'd end up with really weird and whacky ways on how processor design should look like

now that things are pretty much de-facto standardized I can see why people are willing to allow certain kinds of UB if the behaviour is farily predictable

[low vault]

ive heard of like, not 8-bit bytes, weird integer sizes (24????), not using 2s complement, different Floating point reprs, etc.

[low vault]

e.g. I think it's okay to use gcc extensions in code even though it's non-standard compliant

maybe i should watch 👀

maybe ill listen while eating

and fixing my broken bed LOL

WTF LOL

yeah

but I think generally "gcc" targeting "intel or amd" is resaonble

that being said

MSVC

lol did you know that windows uses 16 bit characters? fun

I spent 3 hours debugging that one time

blobspin

[tranquil wagon]

Wait what? I’m almost 100% sure that msvc has 8 bit char type on every machine I’ve used

What architecture were you compiling for?

Or were u using wchar_t or smth

@rose holly I found this cool cheat sheet on value types btw https://github.com/jeaye/value-category-cheatsheet/blob/master/value-category-cheatsheet.pdf

[low vault]

Don’t rmb exactly, but it was like Win11

But yeah a wchar_t snuck into my code when I was using std filesystem

It was hidden in a typedef

[tranquil wagon]

Yeah windows typedefs can be tricky

[low vault]

I did not expect wchar in file names 😭 😭

Taught me to Wpedantic

I thought pedantic > all

Real kicker is werror tho

[tranquil wagon]

Normally I just do wpedantic wall werror

Idk if all three are necessary tho lol

And then when I get an error I don’t like I do -wno-…

Hahaha

[low blaze]

do trader recruiters bat an eye to frontend focus swe

[vague forge]

Cpp is cool

[fresh swallow]

Holy DE Shaw internal recruiter reachout

Prolly not gonna respond

I'm not built like that

[fresh swallow]

If they asked me anything about python the answer would be simple

"I don't know"

[dire finch]

ahead of its time for real

[grim sigil]

if i got a bbl would it help me get into quant

[zenith panther]

nah

cpp some trash

fr

[vague forge]

why do u say

[zenith panther]

yucky

[low vault]

[dire finch]

the w in wchar_t stands for We Gave Up

[low vault]

😭

personally i think it stands for what the FUCK

[dire finch]

windows nt remembered CJK characters but forgot about 𒐫

[zenith panther]

have you been using rocm?

i ran into this issue because AMD's hipify script expects utf-8

but windows was defaulting to utf-16

[tranquil wagon]

That’s what the w in windows stands for

(I’ll still use windows for the foreseeable future)

[prisma ocean]

Anyone that has interviewed with Jane Street willing to give some insight on the interviews

[tiny sleet]

how will they know if it's a different company

also that's a huge w that your dad is also a quant

up and coming quant legacy

[tiny sleet]

how do they know they're your dad though

unless you have a super uncommon last name

[lethal apex]

Linux community can’t ever convince me to become a dork

If my os doesn’t have spyware disguised as AI features I don’t want it

Not like another firm

I’m probably misremembering

[fresh swallow]

2 yoe at mid firms I guess

[vestal carbon]

anyone has advice on how to prep for citadel QD technical and onsite?

[fresh swallow]

Just lock in bud

[gleaming mauve]

lc n cs concepts

[tiny sleet]

lc?

really?

are you talking about leetcode

or is there another lc for quant i'm unaware of

[celest anvil]

Yes it’s called Codeforces

[tiny sleet]

oh that i've heard of

i mean something by the acronym lc

[terse barn]

is he finally leaving the old head place

[tiny sleet]

cause i though leetcode is mostly irrelevant for quant

[terse barn]

need to start 💀

im still on lc

[terse barn]

nobody is asking anything harder than an easy ish leetcode hard

for most firms

unless u get extremely unlucky

like u can definitely stack at least 8-10 quant swe offers without knowing anything beyond leetcode mediums and an intro OS class

[tiny sleet]

i see

so at the interview stage they don't actually expect quant knowledge, just programming and math abilities

[terse barn]

what role are you even talking about

[tiny sleet]

they ask a lot of probability theory questions though right

[tiny sleet]

quant

[terse barn]

quant what

trader or researcher

[tiny sleet]

just in general

[terse barn]

?

[tiny sleet]

so it's completely different for the two?

[terse barn]

have you ever even applied to a role lmao

[terse barn]

yes and theyre both different from swe

[tiny sleet]

no that's why i'm asking lol

[terse barn]

u should at least read job postings

and see what each one is about

[tranquil wagon]

They are completely different jobs

[terse barn]

leetcode is kind of useless for qt, required sometimes for qr

[tiny sleet]

i see

[terse barn]

but yes those are both more mathy

usually probability/stats stuff ive seen linalg before too

[tiny sleet]

it's mainly differential equations and probability theory right

[terse barn]

i think the only diffeq thats even kind of relevant is for like options pricing/risk stuff but they dont expect u to know that coming in at most firms

[tiny sleet]

and then stochastic calculus too right

or nah?

[terse barn]

potentially

idk that much

im a swe

[tiny sleet]

i'm still deciding my path and i'm mainly interested in computer vision, but quant sounds cool too

nah

who told you that

[terse barn]

if ur interested u should definitely recruit for both

better to have options

[tiny sleet]

yeah

i honestly can't decide between the two so i'll probably just take up both to the best of my ability

[terse barn]

orz

didnt he have cit

[tiny sleet]

yeah i'm doing that right now

me and the other student are new so they're just having us do basic stuff first

but later the plan is to contribute to their paper

and hopefully get that into a top security conference (the research is on security in cv)

that dudes kinda annoying though right

i heard he's extra asf

oh alright

[grim sigil]

me

i do not plan to do contests tho, i feel like the leetcode ui is cleaner for implementing

i just psuedocode codeforces for the patterns and implement on leetcode for the practice

[tiny sleet]

is he saying he doesn't want to do contests just cause of him not liking the ui

egregious statement

if only i could do that with school

[meager panther]

Hey

I have an interview

For a quant developer

Cpp

How to prepare for it

[tranquil wagon]

Know all the stl data structures well and the general idea behind how they are implemented

Also move semantics, smart pointers, and concurrency/synchronization stuff

That’s probably it on the cpp front, depending on firm they may ask more OS stuff or Leetcode as well

There’s probably some stuff im forgetting but I think those are the main things

Also I guess templates and virtual functions

[lavish swift]

has anyone done the phone / 30 min round for GSAM quant strats

[grim sigil]

😭

[grim sigil]

the only thing i really like about codeforces versus leetcode is that the problem ratings have difficulties, mediums are too easy, but hards can be like 2300 and that's too far

makes it easier to track progress

and the proofs for the solution

[low vault]

ngl ive never seen a hard that's >=2300

[grim sigil]

https://leetcode.com/problems/cat-and-mouse/description/

[grim sigil]

i dont think that would work because the shortest path isn't necessarily optimal, a component of the solution depends on the fact that each player has to move each time, there can be situations where the cat reaches the hole first, but the mouse still wins

if the cat is on the hole and the mouse is adjacent to it, the mouse will win

[neon mirage]

Listen to yourselves man is this what the world has come to

Arguing over cats and mice

[tranquil wagon]

This makes me feel ngmi

[vague forge]

What is y’all’s motivation for pursuing quant

Money

[unreal rock]

pretty such sums it up imo

[vague forge]

Lol

[vague forge]

What the difference in desired qualifications for quant swe compared to other competitive swe roles

I also enjoy cpp

[warm sinew]

Hey guys, I’m studying math finance + stats — just wondering what kind of internships I should aim for if I want to end up in quant trading?

[dire finch]

you should be aiming for quant trading internships

whats a cht

WTF ORZ

i havent gotten that far...

[low vault]

oh you don't need cht for that

oh

for NlogN?

i would kms if lc wnated me to do that prob in NlogN

[dire finch]

@low vault uwu

[low vault]

oTz

[dire finch]

what is oTz lol

kowtow under table?

[low vault]

ORZ -> OTZ -> ??? -> oTz

weird capitalization ig

not sure what i was aiming for originally :p

[dire finch]

under the table is okay

[dim ivy]

How much does GPA matter for Quant? What would the gpa cutoff be for someone who goes to Rutgers University

[tiny sleet]

the quant roles are quant swe, quant trader, and quant researcher right

[warm sinew]

Thank you thank, but is it possible to get the quant internship as a second-year student without any relevant experience?

[dire finch]

just be smart orz

and go to good school but if you're smart you should be at one anyway

[warm sinew]

Iam in a target school, so this part is fine

[dire finch]

ok

where is issue

[warm sinew]

So do you think I should just be looking for quant internships now?

[dire finch]

why not

[warm sinew]

Oh because I thought it’s pretty hard to get it now😭

[dire finch]

so?

[warm sinew]

So I thought I might need to do some other internships first before doing quant internship,

But it seems like I was wrong?

[dire finch]

i agree

if you do not have enough on your resume to show that you are smart maybe work on that

[warm sinew]

Yeah I don’t think I have enough experience now

So what other internships do you think I should do some first

[dire finch]

ML research

idk bro

[warm sinew]

Thank you thank you

[tiny sleet]

do you guys think learning to be a quant trader as a source of secondary income is a good idea, as in doing it for trading on my own instead of to work at a quant firm

[neon mirage]

Just invest in index funds bro

[mellow aurora]

Brother you do not have any job yet

What the fuck are you talking about

[tiny sleet]

i mean for the future

cause i'm interested in both computer vision and quant

so i'll be learning both

when i say secondary source of income i mean second "job"

mainly doing it cause i think it's cool

[sand vessel]

Bro what

Traders have like the most elite data and tools

U can’t just be a “quant trader” on the side

u can trade sure

[zenith panther]

😂

[untold prawn]

they're gonna make a movie ab him
wolf of quant street

[lethal apex]

I’m a part time algo trader at HRT then I leave to work at my main gig at Walmart Labs

[untold prawn]

wolf of john's street

[tiny sleet]

i see, so the only option would be to do it as a career

unless i first make enough to buy my own servers

[tiny sleet]

nah i was asking cause idk anything

[sand vessel]

I can tell

[near knot]

Is there a job board for summer 2026 quant internships similar to the simplify one for CS internships?

[astral jungle]

im a freshman at a t3 school for quant who got in for mostly bio & linguistics related things and decided i want to switch my major to studying math/CS over winter break. i have some basic cs experience w/ python, js, and R in the context of data science, and im currently in a lab thats using statistics to predict epileptic seizure time, and im helping transfer their codebase to python. dont have much math comp experience except aime x2 and a difficult proof based math class im taking rn. other than that ive joined my colleges poker clubs and quant traders club. how do i lock in (in terms of personal projects, general studying, etc) to land a quant internship asap

[vague forge]

my name jeff

[sand vessel]

Ur ngmi

[lethal apex]

freshman at t3 got in for bio/linguistics and want to switch to cs

go for faang should be easy fresh/soph

[safe yew]

congrats on cal buddy

[astral jungle]

not t3 cs school

[safe yew]

congrats on penn buddy

[astral jungle]

not penn either

[safe yew]

congrats on cmu buddy

[astral jungle]

nope

[astral jungle]

^

[safe yew]

ah right

[astral jungle]

what are the top 3 quant schools in ur eyes

[safe yew]

forgot

[astral jungle]

maybe im overestimating

[safe yew]

not NYU

[astral jungle]

no

can u just give me advice man

[safe yew]

what role do you want

qr

qt

qd

swe

[astral jungle]

qt

[safe yew]

i will do you a favor

check your dm

[lethal apex]

Uc irvine uc santa cruz colorado school of mines

[zenith whale]

what is a t3 school for quant lol

none of the schools that would reasonably be t3 "for quant" admit by major like that

[astral jungle]

it doesnt admit by major

[zenith whale]

ok

[astral jungle]

i just mean my activities were all tailored to those areas

[zenith whale]

i see

[astral jungle]

mit stanford harvard?

[zenith whale]

yeah that would be my 3

maybe replace stanford with pton

but same thing

[astral jungle]

harvard

[safe yew]

you just doxed yourself

[zenith whale]

jsut take the hardest stem classes, learn to code well if you're interested in research or dev

do research

[safe yew]

i mean harvard is harvard

everyone knows harvard

harvard passes hella recruiter screens

[zenith whale]

ur not gonna get passed over because u go to any of those schools tbh

[astral jungle]

how do i get a swe / quant adjacent internship for the summer as fast as possible

or just anything thatll help me with qr or qt

for the summer

[zenith whale]

for this summer?

[astral jungle]

yes

[zenith whale]

its probably over

for this summer

[astral jungle]

kk

how do i grind for fall

[zenith whale]

nah

just do research

have something to talk about

[astral jungle]

ok im doing research rn

are there any categories of personal projects i should try to do

[safe yew]

predicting stock prices with LSTMs

wait im trolling

[zenith whale]

is there anything ur interested in

[safe yew]

dont trust me

💀

[low vault]

research is cool

but its so aids

my code doesn't work

and i have no idea why

[zenith whale]

like when i was in college there was a list of open source things i wanted to contribute to

so when i had time i just knocked those off my todo list

i talked about some of them in my interviews

it was reasonable

i mean

if its on ur resume

[astral jungle]

algo trading

[zenith whale]

and looks interesting

seems fine right

[astral jungle]

dude idk what im supposed to care about

i only learned about quant like 2 months ago

[zenith whale]

sure then go make a bot for a prediction market or something

like a polymarket trading bot

haha

[vague forge]

https://tenor.com/view/money-mr-krabs-gif-18326632

[zenith whale]

some of these prediction markets are really soft imo and u dont need any crazy data to compete

[astral jungle]

ive always really liked math and im taking a really nice math class thats made me want to be a math major, and i figured that if quant lets u use mostly mathematical ability while also making money i should just go for that

also game theory hella interesting

i think qr or qt

[zenith whale]

so math major math and quant are very different

[astral jungle]

not sure

[zenith whale]

just fyi

like most real math majors will hate quant

[astral jungle]

i feel like real math majors also like being employed tho

[zenith whale]

do they

have you met a real math major

it is totally ok to say you want to do it for the money

[astral jungle]

i definitely do

[lethal apex]

"I like algo trading" yeaaaaa sure buddy

[astral jungle]

but if u know of a better job that u can make money with that suits math majors then lmk

because im not going into academia

[zenith whale]

it suits math majors as much as a swe job does lol

[astral jungle]

💀

[zenith whale]

its just loosely quantitative

ur not gonna be doing algebraic geometry at hrt

[astral jungle]

yeah but also isnt the interview process less dependent on swe experience

ok i can work with this maybe

[zenith whale]

nah ymmv for sure

it depends on resume

[astral jungle]

harvard cs is in general really theoretical

to my knowledge

[zenith whale]

ive asked people about implementation details before

because it was on their resume

[astral jungle]

should i just cold email for unpaid internship over the summer

is that the play

[zenith whale]

dude

u go to harvard

just do research

harvard research is better than any experience u can hope to get at this point

[astral jungle]

im worried the lab im in is too bio focused

but there is like an ai lab

[zenith whale]

then do a non bio lab

[astral jungle]

maybe ill change to that

[tiny sleet]

which is better, math major or cs major + math minor

[zenith whale]

it does not matter

[astral jungle]

ig i could also apply to REUs but those seem kind of cooked atp

[zenith whale]

reus are closed

[astral jungle]

L

ok ill get research then

[tiny sleet]

bet

a ton of people said math major is a necessity so i wasn't sure earlier

[zenith whale]

math major isnt a necessity

ppl just say nonsense

or extrapolate from their experiences

[tiny sleet]

yeah i was planning to take probability theory for ml in general

i'm kind of conflicted between computer vision and quant

so for the time being i'm just planning on studying both

[astral jungle]

i think ik who this is lmao 😭

[tiny sleet]

are you being serious

[astral jungle]

but very helpful ty

[tiny sleet]

or is this sarcastic

[zenith whale]

u can def do cv + quant at the same time

[astral jungle]

hes cracked out of his mind tho

im not like that

[tiny sleet]

excellent

[astral jungle]

ill try to cold email startups and get research tho

and im like halfway thru green book rn

[tiny sleet]

so the people that said otherwise were just tryna throw me off

[zenith whale]

why fixate on interning

we've told him this like 4x already

jsut let him do it man

spend 2 days on angellist interacting with ngmi founders as harvard student

incoming swe intern @ "startup" that has been around for 10 years, no funding

(unpaid)

yeah so the thing about quant is that

[astral jungle]

holyy

[zenith whale]

it doesnt shoehorn u into any research

[astral jungle]

did ur friend do math comps

[zenith whale]

specifically

[astral jungle]

wow

[zenith whale]

and for cv u just need to stack research

so its compatible

its less compatible if you're doing like hardcore systems + qr

[astral jungle]

how much does networking play a role

should i be cold linkedining people

for referrals

ok

[zenith whale]

harvard cold linkedining is wild

this is equivalent to making 3m a year and eating ramen off the floor

[astral jungle]

dam

[sand vessel]

mit cmu caltech

[astral jungle]

who should i go to for better advice then

[zenith whale]

i mean fwiw i was a ft quant for 2 years before quitting

[astral jungle]

oh shit nice

[sand vessel]

Harvard research will let u pass every screen trust

[zenith whale]

ive been on the recruiting side of the table

and have seen and evaluated resumes

so even if i extrapolate from personal experience its more holistic than anything people here can extrapolate from

haha

[sand vessel]

lol recruiters have a completely different POV than actual industry individuals- source my recruiter

[zenith whale]

ive spoken to recruiters about how we vet candidates

[sand vessel]

Maybe it’s firm dependent?

[zenith whale]

maybe

but there are certain things people look at

[astral jungle]

there are some pretty competitive data science / ml related clubs here, is it worth spending time on those next semester or should i focus on trying to get fall internships / winternships instead

[sand vessel]

my firm said they didn’t even look at personal projects

It was just school name and prev

nothing else

[zenith whale]

i mean ymmv right

this is because the modal personal project is something stupid

[sand vessel]

wait 5r gives interviews to non MIT?

damn I’m NGMI then

GG

[zenith whale]

my brother's friends at stanford got into jump with his personal project

[astral jungle]

5r screen no mit is insane wtf

good shit

[zenith whale]

well research/personal project

[sand vessel]

Yeah so pinpointing to proj is hard

if ur proj is cracked enough id just put it in exp lol

[astral jungle]

what general kind of research should i be aiming for

like probability research?

[zenith whale]

nah, they literally reached out to him and mentioned the project

[sand vessel]

Bro ANY u can just larp u go to Harvard

[zenith whale]

likle that explains 99% of the variance

haha

im not saying u need to have projects

[sand vessel]

What

[zenith whale]

and im not saying the average or even 80p project is worth looking at

because its not

but if u have something truly good it will be noticed

[sand vessel]

^

[zenith whale]

experience is on average shinier

so ofc people will mention experience

[sand vessel]

but it’s hard to fuck it up going to ivy

like ur guaranteed big tech if u don’t sabotage urself

[astral jungle]

wow

[sand vessel]

what call backs did u get this recruiting szn

[astral jungle]

^

[zenith whale]

u can do both?

[sand vessel]

Yeah networking, focus on both

[astral jungle]

i didnt really know what i was doing lol i just applied to like 10 random data science postings and got rejected from all

[sand vessel]

Apply citadel rn

They still hiring

[zenith whale]

what year are u

and is ur coursework up to par

[astral jungle]

freshman

[sand vessel]

JS and cit still hiring

[zenith whale]

ok u have time

[sand vessel]

u can def pass screen

[zenith whale]

just do research and take hard classes next year

apply but dont get ur hopes up ig

firms dont like sophomores anyway

[astral jungle]

intro cs, multi, linalg, topology/real + complex analysis

[sand vessel]

De Shaw and JS do

he can def get interview at least

Especially if he’s taking topology as freshman

[astral jungle]

ok ill go citadel

should i just grind green book until then

[sand vessel]

at least for qd qd process is ex

Ez

Idk how cracked u r to pass qt yet

[astral jungle]

and do i need cs experience for citadel to like me

probably not cracked enough

[zenith whale]

ppl used to play a lot of games with grad year

the average firm just outright rejects sophomores now

[astral jungle]

im gonna try to get usaco gold and decent putnam by end of year

[zenith whale]

yeah

ik drw crashed out about that stuff

like 3 years ago

gathered all the interns

day 1

asked who was a sophomore

[astral jungle]

oh wow good to know

[zenith whale]

no return offers

haha

2nd year of college

yeah but whos gonna do that

for drw nonetheless

lol

[sand vessel]

lol DRW so ass

[unique cloak]

sup cuh

[sand vessel]

Don’t even apply

CTC is S tier don’t forget

[zenith whale]

ive only heard bad things about drw

also theyre washed

[sand vessel]

DRW is for the ppl who got rejected from good firms

and want to say they r in quant

[zenith whale]

375 for what role

rly lol

[sand vessel]

That’s low no?

[zenith whale]

seems low

[sand vessel]

375 is rlly low for qt

I know devs that make 400+

cit 625

[zenith whale]

i mean

[astral jungle]

wait yea everything in citadel for 2025 summer requires at least sophomore

rip

[zenith whale]

sig 400 is like

dishonest tho

the ev is higher

because of the cit 800 poach

haha

[sand vessel]

wait u right

sig 400 is very dishonest

[zenith whale]

citsec poaches a bunch of sig new grads every year

rightbefore class

and the offer is 800

last i heard

[sand vessel]

Wild take

yeah

only rzn to even apply to SIG

What does r1 mean

Oh

I thought I was misinterpreting

My friend got 600 no nego

qt

but could be Cinderella

can u do qt and swe process at these firms or naw

[sand vessel]

tryina optimise NG recruiting if I don’t get RO

[astral jungle]

do quant firms value icpc

[sand vessel]

I’m gonna try converting to QR ro but if that fails Im gonna try recruiting qt/swe ng

but will only risk QT if I can do both processes

yeah it happens

ro

rare but ik 3 prev interns that did it

at hft

like I won’t apply qt unless I get the dev ro lol

yah which is why if I can’t do both processes I wouldn’t risk just sending it on qt ng

the EV from a NG qt is way higher than their salary tho

[safe yew]

like rn?

[sand vessel]

Ye

[safe yew]

damn i realized they have one posting i want to do

[sand vessel]

How long do they take to get back lmao

I just applied even tho I’m not a co-op 😂

Makes sense lmao

Like very early in cycle

[safe yew]

do universities not have coop programs

like

shouldnt a coop program be commonplace

but from what i see online apparently coop programs are rare?

[low vault]

POV Canadian

😎

[safe yew]

hmm interesting

why is coop rare

like coop seems beneficial in every circumstance

a university setting up a coop program shouldnt be difficult

[dire finch]

delays graduation

like co-op is good if you're ngmi and planning to take 5 years to graduate or something

but if you're smart you just need foot in door for industry and the rest doesn't matter too much

[safe yew]

i mean some people can graduate in 3 years

regardless it offers more choices to students

i believe in letting students make the choice

[dire finch]

there's a lot of logistics associated with it tbh

extra staffing for co-op management, course timings (ex. what if X class isn't available every semester/year), capstone projects or theses

[safe yew]

then thats fair i guess

[low vault]

Sorryyy 😭 😭 😭 😭

[autumn vector]

Chat, Is having an experfience of developing and optimizing compilers relevant exp for SWE in HFTs/Quant firms?

[lethal apex]

Jane Street has a compiler team

and compiler knowledge very useful for low latency

[tranquil wagon]

Yes, very

[safe yew]

yes

do you know ml compiler

thats also in demand afaik

[fresh swallow]

100%

[low vault]

What if I don’t know compilers

[gleaming mulch]

yo how much value do options group (headhunting firm afaik) actually provide and do they work with js/hrt

[lethal apex]

anti larp

[meager panther]

Check dm

Broski

[rose holly]

Is everyone here orz

[sand vessel]

lol did they hit u up too

[hardy marsh]

anyone here go through the process with SIG? if u did please dm!!

[spiral rivet]

(43 + 42) * (1193 - 1) =

practing mental math anyone know how to solve this quickly in their head

[dire finch]

85 * 1192 is a little annoying

85 * 1200 is kind of a round number (102000 - 8 * 85 -> 101320)

[sand vessel]

Is trading cooked if I only have quant dev summer before last year

Like

Should I larp grad date and do a trading internship after I graduate or is NG trading even viable

[spiral rivet]

firms usually wouldn't expect you to do this in your head on the spot right?

[untold prawn]

larping grad date prolly gives u a much better chance

[dire finch]

@lunar thicket does 5r actually grill mental math that's so aut of them

[dire finch]

@mint aurora bro u cant just delete comments and then leave me out to dry like a lunatic

:(

[mellow aurora]

5r grills hella bs

[limpid pulsar]

nah just OA

[fallen grotto]

gpa matters a lot more for qt compared to qswe right

[tiny sleet]

what kind of mental math is usually expected during these interviews

[rose holly]

depends on firm

SIG does basically no mental for QT rounds

[tiny sleet]

what is the greatest extent of it

[hardy marsh]

do u know abt sig QT intern process?

[rose holly]

did in Oct last year but rejected after super

[tiny sleet]

by this i mean what's the most mental math that is typically asked

[rose holly]

cant really say with confidence cause personally havent done any rounds with focus on that but i guess 2 digit multiplication should be the worst of it

honestly the mental math is more for quick EV calcs if anything

at least any of my processes very rarely involved some dude asking me whats 78*32, and more the general problem type would require some degree of quick mental math

[tiny sleet]

really?

oh nevermind

i was worried

[hardy marsh]

do you mind if I dm?

[tiny sleet]

i thought it would be some numeric integration approximation done mentally

[rose holly]

yea fs but not sure how much i can help tbh lol

[hardy marsh]

no worriesss, n thank you😭

[rose holly]

imo most questions for QT boil down to any intro level prob + stochastic course flow

[tiny sleet]

yeah that's gonna be a big focus of mine in uni with the classes i take

that and computer vision/some general ml courses

[tiny sleet]

in how much time would they expect an answer to this level of mental math

[rose holly]

depends on problem, usually should averaging 5-8 secs, but this depends on firm again

[tiny sleet]

i see

[rose holly]

like for IMC they literally didnt gaf that I didnt give answer

[tiny sleet]

5-8 seconds is wild

[tiny sleet]

oh lol

[tiny sleet]

doable though, might just need some practice

[hardy marsh]

some places r more chill i hear like give up to 30 seconds

and then some to like tests like how many u can do in a set time

[tiny sleet]

oh 30 seconds is generous asf

what do they expect in terms of projects

like what's an example of a project that would be sufficient in complexity for the average quant firm

[rose holly]

wdym

[cold heart]

not sure about qt, for swe i just had one simple ml project, but i dont think they care about projects that much

[mellow aurora]

5r oa

Probably

[tiny sleet]

what would they hire a new grad based off of

other than which school, relevant coursework, and gpa

[tiny sleet]

?

what's 5r

[mellow aurora]

Isn't this also cooked

Like

You had intern

Didn't get ro

[tiny sleet]

i meant for internships

wait my bad i shouldn't have said new grads

college students in general

i see

[mellow aurora]

Like if u interned somewhere and didn't join for ft

It's pretty obvious you didn't get ro

[tiny sleet]

seriously though what is 5r

[mellow aurora]

Google is really cool!

[tiny sleet]

5 rings trading firm?

[mellow aurora]

Yes

[tiny sleet]

oh i was asking earlier cause i thought it was some classification for what they expect, didn't think it's a firm

[tranquil wagon]

@rose holly can u help me figure something out pls

https://godbolt.org/z/1GjMesdxd

I read that the decltype(auto) version of this funciton is better but I've been trying a ton of stuff and i can't figure out when it does something different

In the situations I tried it produces the same code in the template instantiation https://cppinsights.io/s/b534bf3d

The other one works for lvalue reference

And wouldn’t the rvalue reference be dangling

Could u try and think of a code snippet where the decltype auto behaves preferably to the one that returns T? My brain must not be working rn bc I can’t come up with one

[limpid pulsar]

5r has stuff like this on the OA not during interview

Log base 2 of 50! and such

[tiny sleet]

what

this is supposed to be done mentally?

[limpid pulsar]

yea

u have like 50 seconds to do it tho

[hardy marsh]

an estimate right??

[tiny sleet]

it has to be an estimate

or multiple choice

[tiny sleet]

what's the purpose of quant hiring process having this

to assess how quickly we can think under pressure??

[tranquil wagon]

Can you show some code of what you mean

No problem

[fringe stratus]

hi

[wispy narwhal]

@tardy shell have you interviewed with g-research?

[tardy shell]

Nah res rej

[limpid pulsar]

the input is exact answer

[hardy marsh]

oh

[limpid pulsar]

they prolly give + points for close estimates tho

[lavish swift]

Anyone done the imc launchpad phone?

[storm igloo]

what time?

also did anyone apply to the Jane Street Xcelerate Colloquium?

[ivory sun]

was there a link to apply for it or anything

okay genuine question, i want to break into being a swe at a quant firm, how can i stand out to places like jane street for the fall co op

I go to a T100 college
incoming aws sde intern on lambda for ML and infrastructure
prev swe at a bio lab
prev ML research intern at a PhD lab
prev gov research worked with boston dynamics robots

i wrote papers too

making the worlds largest butterfly genome dataset

[lethal apex]

Why quant

smartest minds in country going into quant

buy low sell high

[ivory sun]

i wanna be a swe

not a quant per say

its just

cool

i ifnd it cool asf

[low vault]

Ngl QSWE work isn’t that interesting

[ivory sun]

ik i just wanna do it for a few years

and transfer companies

[dire finch]

bro sees the dollar sign

[lethal apex]

😂😂😂

Save it for the interview

[ivory sun]

on god

[ivory sun]

😭

[tiny sleet]

seriously though how would one answer that question

would i just talk about an interest in math?

(i actually do have an interest in math, i just don't know if that's what should be brought up for that question or if it would be better to talk about an interest in the finance part)

[vague forge]

https://tenor.com/view/money-mr-krabs-gif-18326632

[safe yew]

i have an answer

[low vault]

Ok so u want money

Yenno this isn’t an interview right

[ivory sun]

money and i think working on some of the internal tools would be cool asf

and its good prestige to jump around later on

[low vault]

Uhm

[zenith panther]

i met someone who worked there while i was in paris

[low vault]

What kind of tools

[ivory sun]

aw shucks

[zenith panther]

but i haven't 😂

[low vault]

are you like

JS intern blog pilled or smth

[zenith panther]

yeah it is

[low vault]

[ivory sun]

nope i just know a recruiter

thats all

😭

[zenith panther]

hello plasmatic

[low vault]

Hello wecu 😳

[ivory sun]

jane street isnt #1 on my ng list

#1 is prolly datadog

which i can get i interviewed with them already

[zenith panther]

plasmatic turned down js btw

[ivory sun]

and have a referral

[zenith panther]

orz them

[ivory sun]

orz

matter of fact

or2

got my ass out

[low vault]

Inb4 I regret that decision in a year LOL

[torpid galleon]

Would u happen to know what their int process is like?

[ivory sun]

data processing

[low vault]

Oh huh

[torpid galleon]

I cold emailed recruiter and I have a phone scheduled

[ivory sun]

i fuck with data processing and ML heavy and some of the things she told me that quant firms do with them are interesting

my top 3 for new grad are prolly like

1. datadog
2. Google
   3)Jane street
3. take the aws RO

[low vault]

Honestly congrats on having smth legit to say

[ivory sun]

ty ty

[low vault]

My personal impression is that

[ivory sun]

honestly money is the main thing that drew me in, just for ML and data processing i wanna go to datadog

they pay less but seems so much more interesting

[dire finch]

hey at least hes honest

[low vault]

Quant tends to try and play up the interestingness of their own work from the outside

Bcs they know academics won’t be attracted by money alone

[zenith panther]

yeah that's true

quant work is boring as fuck

usually

[ivory sun]

nah i can fully see that 100% being a quant seems mind numbingly boring

[zenith panther]

also performance engineering is boring at quant

[dire finch]

the citsec guy i talked to said his work feels like playing civ 6

in my head im like... hoe?

[low vault]

I didn’t find it particularly being more compelling than just a regular tech job

[zenith panther]

all u do is wait fo rprofiles

[ivory sun]

thats why id rather be a swe if possible and just work with data and do something kinda interesting

or applied ML

[low vault]

LOL what wait

[ivory sun]

thats really fun to me

[low vault]

That sounds kinda fun

[low vault]

I think if the team you land is a good fit, then you’re solid

[ivory sun]

i just gotta make sure i pass ATS

[dire finch]

he was on a MM desk for some futures so i guess maintaining that delta neutrality really is just civ 6

[ivory sun]

i prolly wont tho

[low vault]

Just my opinion tho I’m a uni student LOL

yea same LMAO

I'm curious, do non quant interns also get paid 100$+ at quant firms? Or they get paid normal amount like 50$~

[tranquil wagon]

I’m personally a janitor and I get paid $1000/hr at Wells Fargo

[valid sand]

a&w over mcdonalds noob

[sand vessel]

https://tenor.com/view/strolling-nat-geo-wild-wandering-walking-around-snowy-gif-20536436

OpenAI on this list

[neon mirage]

My code basically attempts to make a lexicographically smaller string, decreasing K on swaps. Then at the end I check if k>=0. I know it’s not optimal but I’m just not sure how you could ever make

r<r’ with the string “wf” with the above logic

[rose holly]

depends on position, iirc alt positions are usually ER/TDOE which are capped at 200k ft, and intern maybe 20 lesser, but the big crunch is youre cut off from bonuses

[rose holly]

i dont know how true this is? mostly because a lot of work in control theory and RL(which more or less for purpose of qt often is restricted to control type analysis cuz of HJB) doesnt really apply anywhere else other than noisy pricing data

but SWE work is prolly way dif than QR/QT, but the math usually is still novel

only issue is youre capped on whether you can publish

signal gen or arbitrage as a framework in general is still a very active topic of research and quant firms literally just deal with those problems on a daily basis, and realistically being in academia and just re-analyzing public datasets from 30 years with limited insight into derivatives youre pretty capped in what you can do

https://www.edwardothorp.com/books/a-man-for-all-markets/

[warm torrent]

Thank you for your answer! What does tdoe stand for? And specially I'm looking at a software engineer full time position

[grizzled oar]

tdoe is trading desk operations

[low vault]

(FWIW I was referring to SWEs, but fair point, I suppose a similar argument can be made in favour of SWEs who do low latency work)

I think most HPC applications nowadays are on GPU (b/c of the hotness of ML and whatnot), and so there isn't much demand for super efficient C++ code on the CPU for example

I think outside of like, snowflake (even databricks doesn't really use C++)

[dire finch]

the c in cuda stands for Can You Stop Writing Metaprogramming Code It Bloats My Binary Size

[low vault]

top firms pay a lot

shaw pays like 120/hr for swes

js is like, also 120 or so?

etc. p72/cubist is like 90 or so and hrt/cit are around 100 something(?)

[low vault]

LOL

😭

[gentle robin]

how impressive is meta summer and zon fall, is it enough for quant dev roles

also, is it that much better than just doing meta summer

[ivory sun]

trading desk operation engineer

its back end and low level stuff

[rose holly]

uhh not sure about dif firms, but JS/Optiver TDOE is usally jokes lmao, you're more data processing than anything

[neon mirage]

But r’ is rhe reverse of r. Which is already fw

Am I trippin?

[dire finch]

fw = fw though

doesnt the problem ask for strictly less than

[dire finch]

edit: no, their definition is <=

oh i agree then

[tardy shell]

why would companies give cc?

like the ones for eating and stuff

[neon mirage]

OH I understand it now

Thanks king

[low vault]

ohmmmm

[zenith panther]

databricks uses c++ for photon

[low vault]

yeah but i was told that they have very little C++

[zenith panther]

most of it scala i think

but for the performance criticla stuff

[low vault]

oohhhh

[zenith panther]

it's in c++

[low vault]

honestly scala is kinda fire

[low vault]

ye

kinda depends on how mission critical each individual componnent is

[zenith panther]

orz..

[lethal apex]

ye this makes sense

[lethal apex]

True about HPC generally, but does that really apply to trading firms/hedge funds? The only real example I can think of is High Flyer.

and can you elaborate on what you meant by “there isn’t much demand for efficient C++ code on the CPU”

[spiral rivet]

anyone know anything about schonfeld? would it be worth going amazon soph swe ---> schonfeld junior swe if I want to recruit for QT/QR senior summer between masters or would it be better to just stay at amazon

[lavish swift]

Which team

[spiral rivet]

investment sciences

[ashen zephyr]

hi everyone Im new to finance can anyone help me to learn financing from scratch please

[rose holly]

i know a lot of couple of people from targets/semi-targets who got SIG/Akuna/Tier 2 firms with Schonfeld SWE experience

[dire pagoda]

Create an LBO model for the Israel acquisition of the gaza strip

[spiral rivet]

you think they wouldve done better with zon + schonfeld or like zon + meta/google for QT recruiting?

[rose holly]

dont think it makes a dif lmao eod its all just signalling lmao

passing screens usually the light part for Tier 1/2 QT, I know people from non-target with fucking waiter on their resume who work at JS/IMC

JS admittedly screens more intense now, but as long as you have something on your resume that just screams 'I AM REALLY SMART AND CAN MAKE YOU MONEY' youre literally fine

[limpid pulsar]

They give phone to many people

So it likely is

[terse barn]

excel and python scripter

[terse barn]

more than enough if it’s for quant swe intern

otherwise idk

[ivory sun]

Real

Is previous zon, Ml research, gov research, and internship at a lab doing SWE enough for quant SWE intend

Anyone know what the interview is like for citadel nxt rounds? Is it like leetcode style?

[low vault]

at least it feels like most job postings are like

higher levlel programming language

often python

I just don't think there's that many applications where the latency/performance of a single machine is so important that you have to optimize it to that degree

or at least, outside of library code (which will usually be small teams at most companies)

your average tech company will be mostly using python, java, go, or some other high level lgnauge

Anyone done experienced dev interviews at DE shaw

Also do they blacklist if you fail

Maybe I missed the connection to “quant firms play up how interesting their work is” because im not following. I would say the people who do low latency at these firms are almost always passionate nerds like william

but I could see a point made for swe which I find boring in general

[fresh swallow]

Yeah swe blows

Should've done IB

If you're a freshman or sophomore in college change course

Or any other career field which entails getting to do things for free with/as a potential client and also interacting with women in your daily life

[dire finch]

20 points more in SPY until it's a flash crash (-20%)!!!

we witnessin history

[gentle robin]

i am going to be applying as new grad

[terse barn]

oh it’s probably cooked then

[terse barn]

do lc until u can comfortably solve any med and solve most hards within 20 mins

[agile kraken]

is it only lc?

like do i need to know anything else?

and is there any tips on getting past resume screening. Im interning at oracle this summer

[terse barn]

ur chilling

you’ll prolly pass at least a few next year

[terse barn]

just lc is enough for like half of quant swe intern jobs lol

otherwise u might need very base level OS knowledge or maybe networking/system design for like 2 firms

[agile kraken]

ok thanks bro

[gentle robin]

wtf

[fresh swallow]

You're still in college

When you graduate you'll realize
