Yea
So they just play a shit ton of hands and then keep track of the win rates for each situation or smt? But then yk ur win rate, but how do u know the appropriate betting size then
Since ur betting size could influence the outcome
Found an open source python framework that was published by a uni research team to simulate games
Yea, I’m just tryna create a heads up one rn
Doing for the challenge, not necessarily profibikity cuz so many heads up bots exist
Ye but I’m still confused on how creating a poker sim is relevant to creating a solver
Yea I alr implemented CFR, but I’m tryna implement deep CFR now
No I implemented CFR by myself
But I used another package to like calculate the utilities of each situation
Yea, like it has to visit each node
Yea
I mean u could just create all the game states ahead of time
Yea
So u would have to do manual abstraction or deep CFR to use ML to do the abstraction for u
Which is where I’m at
I’m tryna implement deep CFR
Card abstraction
Cuz like u said, u can’t simulate all the game states cuz too many
Oh yeaaaa Monte Carlo tree search
That’s what I was also thinking of also implementing
Dyt it’s feasible to code up a heads up poker limit holdem bot?
Using MC CFR on a laptop
Do u have any good resources I can access about MC CFR?
Cuz I haven’t found any good things to read that isn’t a shit ton of unreadable formulas
Wait but the cfr I did I created the entire game tree and then would iterate through the entire thing
So I wouldn’t create the game tree ahead of time?
I would just add on as I iterate through dif situations of poker games?
But even after like a shit ton of games, I still like wouldn’t be able to iterate through every game state right
Like after a week of simulation, I would only cross like 10% of possible game states?
Ah I see
I mean I could just abstract the betting sizes right
And then when playing NLHE I just map the simplified betting sizes to whatever the person does
Ok so to recap, I just use the sim package to simulate games, and then for each info set in the given game, I update the regrets afterwards?
Wait what’s a full policy grid
lol sry for all these questions, I just started this shit 2 weeks ago. I’ve mostly played brick and mortar games and wanted to try coding this shit
Oh interesting, so like the thing that holds the regrets, strats, etc?
Also wait even if I abstract the bet sizes, I would still be no where near visiting all the game states. So like in a given game, wouldn’t the bot have no idea what to do if it’s never simulated that state before (so like the probability vector for the actions r default 1/n)
Still, capping them at 5 bet sizes is still not rly feasible to visit majority of states
Oh wait what
So it doesn’t actually have to visit all game states? Even if the game is abstracted
Oh that’s rly interesting, I’m gonna try that then
Thanks for ur help, I couldn’t find any good resources on MC
Wait but if u don’t create the decision tree ahead of time and instead create them in real time as u update the strats when simulating dif game states, then wouldn’t u arrive at the same problem of the info states sometimes not existing in some cases? Like it being more likely on later betting streets
Just vanilla cfr or MC cfr
I read into some of the theory, but mainly focused on implementation
So I was able to implement it w/o references
So I did preflop for proof of concept, and I iterated through all possible info states and then would calculate the EV for the utility function of the dif states
Yea, that’s how I was able to create all the game states ahead of time
Wait so what happens in the situation if ur on the river betting round and you’ve never been in that game state before
Oh rly? Wait how
Oh okay
Do u have any website recommendations I should check out
Or that u used
Yea I abstracted to only 5 dif betting sizes
So I could pre create the entire game space
Yup
It was like 1.6 mil info sets or smt
Anyone have experience with or ideas for systems related projects for a quant swe resume?
anyone do a technical interview for stevens capital management
For qd?
is it with the director of low latency
yes
oh i had it
likelihood of optiver sponsoring? Heard it's team dependent
@quiet meadow dyt external sampling or chance sampling is easier to understand and implement for MC CFR
Wait wdym, I thought u read through the MCCFR papers? Or is chance/external sampling a variant of MCCFR
Does any company pay for business class travel
ftx
asserting dominance
but return wasn't 1st
its quant dev same as swe
anyone done final round for two sigma swe?
qd is a superset of swe, it's basically swe on a research team with possibly some research work
that website was down as well from what I read on the reddit post 
Morgan stanley app dev nyc intern or capital one tip intern Philly summer 2024??? Im confused what to choose. Trying to go into quant eventually.
how was it? i have it tomorrow and i’ve been doing a bunch of graph problems
did u move on to the behavioral after
Do quants that aren't optiver js hrt ghost for FPGA? Highk don't rmbr which else I applied to lol
dudes speaking another language
i heard sig pre-screen is not gca but i received a SIG Pre-Screen General Coding Framework codesignal
does this mean it is gca still or their questions?
ye its guaranteed technical if u do it
anyone going through optiver process rn?
last year it was lc easies
ya
Don’t they do combinatorics trivia
Has anyone done SIG QS/QR intern onsite?
not for oa no
telugu ?
didn't jump have a bad year
so dont work there anymore cause of bad year?
same
this tracy girl must be a JS/Jump person haha
anyone know the questions for beat the odds of optiver oa
yeah
what’s the chance of getting a head if u flip a fair coin
also this comes up
lol
i love hormone replacement surgey too
True prodigy
is Discover Citadel a quant-focused / tech event or more of a fundamental investing typa thing?
shiiiii did the Trading discovery open yet?
i only see technology expression of interest idk if thats just SWE or SWE + trading
damn
so i missed it :(
no
whats a good book or resource to learn about equities if I just wanna know some stuff for background. wont need it on the job since im a swe but i wanted to know the basic term and concepts since im on equities team
be a participant in the markets, do research, read case studies
it helps connect the terms & their significance
how does this happen
Hi guys, I’m a freshman majoring in cs + math with a minor in statistics, do y’all have any tips on getting an internship at JS/HRT/Citadel/Wolverine trading?
bro threw in wolverine trading 💀
but prolly just get hella good at probability
do some zetamacs to get fast
study green book
Bro said Wolverine 💀
for js in OCaml we trust
can I DM?
kiss me
Hi guys, I’m a freshman majoring in cs + math with a minor in statistics, do y’all have any tips on getting a quant internship at JPMC/C1/BOFA/Wells Fargo trading?
No
yup
What’s that
Hi guys, I’m a freshman majoring in cs + math with a minor in statistics, do y’all have any tips on getting a quant internship at JPMC/C1/BOFA/Wells Fargo trading?
- What masters course is more suited? I initially thought Quantitive Finance is more suited but heard is more of options pricing which is not really what quants deal with.
As such some suggested Statistics, is this generally more relevant?
just finished a math questions OA for SIG, for the Quantitative Research and Quantitative Systematic Trading positions. has anyone else done these and know what the process/next steps look like
Dmed
Has anyone found success cold emailing recruiters to get into the interviewing pipeline, particularly at smaller funds?
yeah there’s a shared blacklist between firms
only the big ones though
?
recruiters talk
its pretty believable but it would be more recruiters from different companies having a shared blacklist not companies if that makes sense
big market players I assume
Mfs really think these firms are gonna collaborate to blacklist some random people and risk a lawsuit/bad rep for no reason other than to spite a guy they don’t care about 
Ik there's def a lot of connections between recruiters, Ive been referred from a recruiter to a recruiter at another firm after failing rounds for example. I would be hard to have blacklist database but Im sure if a person cheated for example a lot of firms will know
Idk the laws on this but seems similar to why your previous employer won’t share negative feedback about you, you’re risking that information being the reason you suffer a loss financially by not getting a job
I personally wouldn’t risk it but who knows maybe it’s worth it to those guys
They never will though because why would you a billion dollar firm risk a ton of money to screw some rando over for a job
Idk maybe I’m overthinking it, it seems like a lot to lose and little to gain to create a blacklist since all the things worth blacklisting across firms for like illegal shit would be known or caught by bg check
theres no risk lol
? Isn’t the reason no one will ever give any feedback is because you’ll still spend money defending a suit if a candidate wants to file one
there’s a lot to gain
hiring bums is a huge negative
What is there to gain for citadel to tell xyz firm that they don’t want this candidate again
to keep good relationship with other firms
I see that’s a good point, I never really thought of that kind of relation
I guess it really only matters if it’s false like would you want a middle manager who likely has a vested interest in appearing to have made the right choice in not hiring you/firing you to say what is appropriate and provably true to HR/another firm
But I do see the gain here, interesting that they could do it probably entirely without anyone ever knowing due to how small of a community HFT recruiting probably is
yep. thats why above I mentioned if that list exists its probably only within recruiters but not like an official things for a firm as a whole
Yeah I imagine that’s a good middle ground, verbal through stories/anecdotes but never official
ye
I can’t imagine anyone here would end up there unless you do something out of line
and its also good in general to not let crappy people in. an extreme screnario would be not telling cit not to hire a candidate with tendencies for cheating the market and he'll spoof, fuck a bunch of companies over (including the one that didnt tell cit), get cit into a lawsuit
its just a loss loss
I imagine those cases are already known without even having to explicitly blacklist
Like that random guy from two sigma suing his firm already got outed before suing for the massive losses he got blamed for
give ur offer to me
better than being deported
whats mm
also dont lie, give me your real offer
Should I do masters to land internships to pivot into qt intern or should I land ft job to pivot into qt ft?
Would you guys say code forces is the best way to prepare for trading firm OA’s, if not any suggestions?
codeforces defo good, but i haven’t had any issues w quant OAs after grinding leetcode med/hards
Did you do HRT oa?
What role?
I opened it and closed it immediately
Isn’t it just like millennium limited partners
The more confusing one is mpg which they use for hiring
tbf no, ig that one might have been aids
did all the other ones
I felt like such a genius for figuring out the base conversion one
Oh
Full time?
anyone know if new grad quant is non existent?
it doesnt exist
give up
do an mfe
wdym
its better to go for intern instead?
u should just go for phd
im not doing qr though
are you at a t5
and do u have any math awards
or competitive programming
otherwise just dont apply
i mean theres people from my school who were able to break into quant new grad and they didnt have any of that
ive seen cases from people who go to non targets and were able to break into new grad without any of that as well
you just gotta be good enough to get the interview, and pass it
@zenith panther i feel like u have a very skewed perception of it
then youve answered ur own question
not sure why u asked in the first place
i asked this one originally, but idk which is better out of the 2. which is why i followed up with the other q
plus i wanna see other people’s perception of it not only mine, expand my horizon
idk if all quant firms take new grad as well, i know js doesnt
me?
does anyone wanna mock, I do mediums - hards in python and my goal is a fang company
Anyone did sig qr/qs final?
5r still hiring this late?
What do recruiters look for in a resume for trad ops roles?
for quant dev, its all cpp fs right python frowned upon?
who told you this
ive seen it myself in itnernviews
don't know if python is fs frowned on, but anecdotally most of my interviewers were happier when i used cpp
Can you send resume
A bit late no?
Do you guys have any recs on cpp textbook?
Thats comprehensive?
like ones that explain C then go into CPP?
is 3.91 gpa good enough for top quant screens
no
Lmfao
Any advantage/difference working for a small sweaty shop (Headlands/radix/aquatic/vatic) vs regular prop shop or HF as a qr?
thanks redpocket
fr?
in terms of what? from what i've seen you get more breadth of knowledge/experience and higher pay at smaller shops
but longer hours, work schedule is less stable, and more pressure
The type of work/comp
i have a friend that did qr intern at citsec, hrt, and radix, now full time at radix. type of work is more team-dependent rather than company dependent. pay was radis > hrt > citsec
Tf can your friend teach me to be himothy as well
But still thanks for some form of insights
does citadel wanting to schedule another 45 minute interview after the onsite mean i’m borderline between moving on and rejection?
yes
aight sg
anyone done final round behavioral for two sigma swe intern?
anyone done interview for peak6 bootcamp?
Anybody heard of QCP capital?
what to expect for sig discovery day tech?
i know a couple ppl that had a 45 min interview with a hiring manager after onsite (including myself). we all got the offer so i think ur good lol
Hi everyone, do you think I should still apply to Citadel NXT program if I only have ~1 YOE (full-time). The website lists 2-6, but could I get in if I also have a referral?
Do u think the outcome of applying can be worse than not applying?
<@&868936794601828492>
Hey, i would like to learn how to make $30k. Would you mind if i kindly dm you?
@leaden temple
any1 know des res process
Anyone know if there’s a GPA cutoff for these shops with 3 yoe at Meta?
are there cit boxers as well
Does anyone have any info on optinomicon? Have my interview coming up
anyone did JS TDO new grad process?
did phone yesterday
i think they resume screen after oa
don’t need a perfect oa score to pass
2 research 2 internships basic projects
f500 and at a uni
nothing crazy
I only got 2 and half the test cases
For discovery tech
And got phone
It’s mostly resume
dm
has anyone heard back after oa for sig soph discovery day
no stop the trolling
ye phone
yeah its 4 questions and i got two of them plus half of one of them and none of the last
im not the best at coding
They told me there isn’t a tech in the phone screen
Yeah I did the phone interview thing yesterday
what are some good projects for quant 🥺
to do app
How long ago did u submit the OA and how was the phone
Phone was chill but I said a couple dumb things lmao, I did the OA on new years eve
Sure
Yeah pretty sure it was
Anyone did JS TDO new grad process?
@quiet meadow i finished the MCCFR alg for HUNL poker, but i'm having problems reaching some of the buckets (like situations where there's quads or a straight on the board) since they rarely happen so the bot is unable to create an accurate strat for it. do u have a solution to touch upon these situations that rarely happen while still maintaining the sampling frequency concept in MCCFR?
@blissful kite have u done cfr stuff too?
if anyone's gotten to the head of hr/engineering head/cto step of the two sigma swe internship, please dm. got a few quesitons about how to tell 2s about competing offers
did not know they dont nego
they specifically asked to share competing offers for the reason of being "helpful data" when formulating a 2s offer
anyone at js have received their intern swag yet lol
This is a cringe flex
Anyone at Albertsons gotten their swag yet?
no i have been waitin for a month and a half i am j wondering
20 inch bicep
You have an intern discord lol
Why ask here
??
No, they have recruiters in them lol
all the ones i have been a part of was just interns
snowflake
is it not usually a slack?
weird
You get slack when you start or whatever communication platform they use
orz so prestigous
Lol
I’ve never heard of this, do they always send it to you automatically or do you need to ask?
Automatically
Interesting
I know there is a JS discord though because a friend asked me if I knew someone from it
But maybe it wasn’t broadcasted by HR
am sure there is one but doubt i'll know about it until later
tdo isn’t prestigious enough to get invited to a disc 
???
Luckily I don’t need to worry about that because I’m not interning at IMC lol
I’m don’t have a quant internship
I’m a freshman lmao
💀
💀 💀 💀
im dead
no
M. anyways they didnt even ask for size
doubt they are sending clothes
GL
letz do it
woah

Bro you’re cracked
is there any quant open for fall yet
No I said I DONT have a quant internship
cit/js
Cit open ?
i am still confused
they did not ask my shirt size ig TDO's dont get clothes 😭
wait
that's in october tho
i got my offer in dec i think
Okay Mr. Sunnyvale
Was that KN
Congrats on (derogatory swe role)
Are you asking if fall and winter are the same thing? If so, they are not
September-December
does a swe pipeline manager at citadel viewing my linkedin after onsite mean anything
Is it common for regular swe at faang+ to switch to quant firm for swe? Are they at a disadvantage vs new grads to landing these roles. Or is it something that very rarely happens? Can someone please guide a bit if they have any info or heard about this?
no
if u get an email with a call it means smth tho 🔥
nah
not common p sure
getting quant after grad is way harder than internship
no quant exp -> quant firm is kinda unlikely aswell
not impossible
tho
whats the process like after onsite?
i've heard so many different answers that idk at this point
<@&868936794601828492> look what a generous fella
Yes for sure totally swe to quant in a quant firm is almost unheard of imo. I was asking faang swe to quant firms swe
easier but still not common
tho that sentiment is prolly biased by the fact that ppl who wanted qswe wouldve gone to qswe instead of faang
I see, i just personally joined faang 6 months ago and wanting to transfer to quant swe and well, lets see how it goes. Thanks!
From what iv mostly read, the prep for quant swe is to master leetcode with cpp and master OS concepts. Is that most of it in terms of prep? Anything else that im missing out?
Combinatorics is important
Somewhat
And linear algebra
(This is stuff I’ve heard from quant people, personally I don’t have enough experience to testify to it)
combinatorics and linear algebra has zero relevance to swe
is this chat for quant devs also?
Combinatorics way of thinking comes up a good amt of the time I feel
does gpa matter for quant, if so how much
anyone do cpp multithreaded? do you stick with stl or use stuff from boost folly etc
std::thread , std::future , spam smart pointers w cpp 11/14 is this the way to go lol
Use the standard library, std::thread is based off of boost anyways but has the portability of the standard library
bet ty
Stl
Boost is annoying
take a wild guess
Very much
yeah, but if you have faang exp and an overall impressive resume SOME firms wont care
most care yeah, but some you can omit gpa and still interview with a good resume
speaking for swe, idk how it is for trading roles I can imagine they care more
yeah sounds abt right
if there are other 2024 optiver interns, my dms are open 🙏
There's a server for optiver interns
https://discord.gg/WFdNvgWy54
that’s just because wolverine has a high bar because they perform so well
what combinatorics way of thinking comes up when ur making tooling for traders
thanks!
It is dead af
The only new thing that happens is people joining haha
ah, in that case, how did u or were u able to talk w other interns last year before the internship
i assume once it's closer to summer more active stuff will happen
Casework in general is quite common, especially at smaller scales
Made a WhatsApp for our cohort
Do referrals matter for citadel
Just got bbg swe offer, no cpp experience. Not sure what team I should join, if I want to switch to trading/hedge fund
the one you'd enjoy working on
or the stuff that's closest to the exchange
actually I lied
bloomberg dashboards -> trader dashboards might be the move
Try to get put on a c++ team? Pretty sure Bloomberg trains you
so cracked
FWIW I joined faang a bit over a year ago and have gotten pinged for interviews by numerous quant firm SWE recruiters in the last several months, so certainly seems possible if you’re able to clear the interview bar
That’s good to hear gives me hope xD, ty!
if citadel is asking for "competing offers" they mean other quants right?
How do the quant people contact you
what location?
chicago
i told them abt all my offers, but i only got the standard swe offer cuz none were comparable in comp
cit
i heard someone negod with google
and used wlb as part of the rzn
wtf😭
💀
what's your profile like? were your faang projects systems related?
Ik nobody asked but im just gonna say it
These are the top firms ranked by their names (not prestige)
sry if I rated ur firm low, it's just based on name no other criteria
If anything it goes above Optiver
U agree with 1-5 though right 😎
u rated their firm too high
lol
or wait
ur rating by their literla name?
or how much name brand they are
Literally the sound of their name
why is HRT so high
why is virtu so low
It flows off the tounge and it's rlly unique
Basic
Noted, i'm revising the list
Akuna is such a cool name tho
That's gonna be way harder
cuz they're all fkin ass xD
I'll just do top 10
Ok i thought it was cringe at first but I see it now
Top 10 Logos:
By the sound of the name?
nah man im sorry Citadel Securities is a boring ass name how is that no 2
honestly all the generic "trading" "management" etc. should be nowhere near the top
for swe it’s just leetcode mediums + some hards(depending on the firm)
some don’t even ask that just trivia up till systems stuff
for that u can read ostep if u didn’t take a class on it
I did but ignored it, ty for the genuine advice 🙏🏽 also is there a huge pay difference between swe and traders? Curious as to how big the gap is
rlly depends on the firm and what tier the firm is in
some traders at some firms make less than the avg at big tech, can rlly be anything
in general tho usually the traders get payed a bit more than swe’s
since for quants swe’s are more like the support for traders so they aren’t first priority
Makes sense tyty
ye np
in terms of difficulty getting a low tier quant for swe is about the same as big tech tbh but i would argue atp j take big tech
it’s the tier 1 quants that are very very selective
btw im gpa gapped LMAO is that gonna fuck me for NG recruiting so I should probably go FAANG+ NG then pivot?
just apply and try ur best tbh
if u get it for NG then great
if u get faang then yea u can pivot
ppl think after ng it’s over for quant
but quant swes are hired from anywhere rlly
it’s just the interview process might be harder for NG than intern
fuck it we ball, I did a 2Sig interview this year but definitely wasn’t ready at the time but ofc I always get res screened at JS when I’ve tried
JS res screens rlly hard
they also say to not apply the next cycle if there’s no significant improvement lmao
rlly j a toss up tbh
wouldn’t lose sleep over it
that’s for qt trading
u don’t need it at all for swe unless if u interviewing for hrt algo dev
but for qt trading it’s basically like the princeton review version for qt prepping
Gotcha never knew exactly what that was, ty again
yea np
Probably the gamer in me but Citadel is a fortress on a mountain i'm in love w/ the name 😵💫
Noted
I wish
I disagree so strongly
probably
does hrt have traders?
hrt algo dev 😍
Mainly via LinkedIn, one or two via the email I have listed on my resume
My profile isn’t anything crazy, graduated with good GPA from a decent state school, previous internship at faang which was a pretty standard intern project, I’m currently on a backend C++ team which I think probably helps catch interest from quant firms
just basic betting games
Hey @low mural, mind if I dm you about 5r? I sent you a fr
any c++ experts
how do you do network programming
and multithreading is there any good resources , is openmp a drop in for os threads
if ur not using external libs, most networking in c++ is the good all beejs socket programming
beej is goated
im acc working on a multithreaded socket level program in c++ myself
ya in my networks class our prof just said read this for the labs
what job do u want
quant dev?
Any books that yall recommend I read for quant swe internships for the future?
Accelerated C++, OSTEP, Understanding the linux kernel for low latency dev stuff
undergrad probability is prolly fine for QT
QR is don't worry about it lil bro
bad advice
you can get intern offers from most intern places non knowing a lot of this stuff 
rly? every single one of my quant interviews have asked c++ (mostly) and systems/os stuff.
jane street doesn't ask any of that stuff
nobody has rlly ever asked me for C++ specifics, even for C++ roles like radix
really so what would you advise doing? just more LC?
Write more big projects
Code for fun
how easy is it to switch into SWE roles or ML research in industry roles after years as a quant?
are you allowed to do the interviews in Python?
Berkele so scuffed
Do you and normally do all you guys have really descriptive LinkedIn jobs and what you did? Does that help more in terms of recruiters reaching out to you constantly?
anyone here work at cit 🥺
all my quant interviews were leetcode 😹
why
Anyone did sig qr/qs onsite?
bruh what quants?
like most?
lol, this was not the case for me. most of them really went with low level, networking, syntax comprehensive etc
damn
also great music taste 😭😭 who hurt you
Does anyone have any advice for two sigma swe final behavioral?
Did you alr ace the technical finals?
ostep is still a somewhat useful read but yeah you don't really need much besides like very basic systems
was asking for friend but yes i think they finished
Hi friends, has anyone heard of Tibra Capital?
follow up question: how bad is being a platform/devops engineer at a no name quant firm?
Yea the ozzies
Oh shit really?
In regards to SWE career
yeah they got in a lawsuit lmao becasue they got accused of stealing trade secrets since they made money too fast after leaving
Oh I didn't know that that's kinda dodgy
😅
Same
Eh I mean who knows
The industry is full of oppressive non competes and whatnot
Could just be overzealous optiver
#janestreet
Jane Street
@primal shell did someone mention me lol
I did, yes
Juda
prestige
Ligma
Do qt interviews ask about calc, lin alg, and/or did eqs?
Anybody have any experience negotiating more money after signing with another competing. Asking for a friend.
would you take this job at a qt:
What you will be doing:
- Deployment, support and monitoring of new platforms and application stacks - measurement and optimization of system performance
- Maintenance and troubleshooting of our core global platform
Introducing and integrating new technologies into existing platforms
- Liaising with stakeholders and supporting their needs
- Creating technical documentation related to system configuration and operation
🥲
that looks like a dev job description
what really?
sounds like sys admin or devops to me
yea i considered sys admin as a subset of swe

does anyone know the process for 2nd yr quantitative research analyst for 2 sigma? i got an email invite
anyone had peak6 interview?
what to expect for citadel second phone?
Bruh what didn’t u cop
they did last yr
What’s the best way to solve fermi questions?
be omnipotent
Fair enough ig
Annoying for me because im gonna end up my sophmore year with 140 credits lol I guess
then again im not even applying to these places im just here to read
They didn’t accept those this yr
I’m a legit 3 yr grad and my school has a lot of those but they said I was too young
Wait how do they verify hs grad date
Guys, anyone taken the first round Optiver technical interview? QR role. Any suggestions about preparing for it?
Anyone done citadel phone b4 I would super appreciate some advice I've never had a quant interview b4
i got a lc easy
nah phone is the easiest round
i got east hashmap
on-site is harder with harder mediums and potentially hards
they are very rng in terms of difficulty
okay good to know
I'll just prep everything tbh
I literally just started applying and they ask about competing processes but they are the first outside of my RO for next coop and FT after
but that company isnt really at that standard idk if I should put it
swe? got one of the easier lc hards, and then a networks trivia question at the end
beginning was asking abt my projects, and he asked abt technical details and design choices on it
Does anyone recommend any books for learning c++ well including trivia?
for intern?
yea
1 sec
ill type out the prompt
"when one server connects to another server, it establishes a bi-directional channel so that both servers can communicate through that channel. Now when two servers are trying to connect to each other at the exact same time, how do you go about preventing two bidirectional channels from being created"
I'm cooked
whats the answer lol
no it depends on the resume and what u put on the questionarre
so don’t lie on that
doing it rn
they will only ask u what to state u know well on the quessionare and the resume
so don’t cap and say u know OS when u don’t
some shit like that
its joke
yes
honestly bruh it took me like 15 mins, i gave like 5 other random potential answers before getting to the actual answer
yea put os/systems high on the questionnaire
said that have an lock when a server tries to establish a connection, and the lock can only be accessed if the server trying to create the connection has a lower id than the other one, which he said was a valid answer
i.e. server 1 can make the connection to server 2, but not vice versa
lmao fire
honestly got lucky the question was more systems-y than pure networks trivia
well its more like 2 real answers and 3 half baked ones
but thats one of the real onezs
other is three way handshake apparently
don't think the handshake would work in this case? solution would have to avoid race conditions
but idk haven't taken a networks class yet
idk dont shoot the messenger
ye
How long did it take for ppl to hear back after first citadel phone (for swe)
Does anyone recommend any books for learning c++ well including trivia?
Are any quants still hiring for '24? either FT or intern, probably didn't pass Voleon
100% troll account
is there any online resource to study lc questions that utilize some very mathy trick for optimizations?
not the basic stuff on. neetcode
Codeforces has user curated "math" lists
Albeit the problem difficulty ranges
Probably overkill but maybe theres some LC curated lists out there as well
Anyone interviewed for citsec DDM/voice trading intern?
Atcoder is more mathy as well
ama i know the ins and outs of it
why not work on your weaknesses?
How do I learn c++ trivia
QR does NOT build trading platform
Someone teach me the hack for Zetamac 2 digit multiplication takes like 5 seconds 🥴
🤓
Have to get there first
akuna ded
what does that even mean 😭
Wait so why did this guy go through all this effort just to make a troll account lmao
lol
but what about citsec? is that regarded as on a similar level as jane street?
live laugh love hrt
besides hft and market making, is it all just insider trading
Yes, ask Nancy Pelosi
What is Market Making?
Anyone take the optiver hardware OA?
market making is peak insider trading
Can you explain more, I heard this term before but idk what it is
How do you Make a Market?
Huh?

Can u please use more than 1 word to explain this concept
use google poopy head, they basically are middle men, someone wants to sell something at some price but there isnt anyone who want to buy it for that price yet, they are willing to buy it now at that price and sell it later, the market makers compete to give the seller the best prices while still being able to to sell it to a buyer at a profit, to do so they need to accurately price the thing being bought and sold
the purpose they serve is when u want to sell or buy something u can always do so quickly and at a good price
they add liquidity to the market
if only 1 person wanted to buy ur apples today then they could say i will pay u 1 dollar when u want 10 dolalrs for it, if u dont have time to wait for other buyers u will have to sell for a price that is less then what the apples are actually worth, hence the marker makers make the market more efficient
so even tho they are middle men they still serve a purpose
That makes sense
But why do they need to price the security? Cant they just use current price to offer the tighest bid/ask
Would meta or Apple be better for quant recruiting
Netflix
I got reject 
rest is fair game
they need to know the true value to know if they are over or under paying for the security when they buy off the seller and if they will be able to sell at a profit, they need to know how risky it is buying off the seller and what is the likelihood of getting profit. there is a trade off between offering a good deal and getting the contract and being too risky, unless they find inefficiencies in the market the risk to reward ratio will be perfectly balanced and they wont make money
You’re a genius
At the end of they day they don’t really know the true value, but all they can do is use probability to determine their edge?
And in the long run probability pans out I think
ya pretty much, they want to get a better evaluation of the security that others do not know and that they can be confident has more reward then risk. they are doing things which would appear risky but but they researched and found that their pricing is acc not that risky
Do market makers only deal with options or do they provide liquidity to the stocks themselves i.e NYSE
ya if the market is perfectly efficient then the losses from risky contracts will eat away at their profits from risky contracts that they didnt lose money on
im not sure but ig it could apply to more then options, i dont know why theyfocus on options
im not pursing quant but there was a time when i researched this stuff
it’s prob cause there’s a lot more risk management techniques when trading a derivative like options i.e vertical spread
Hedging*
ya maybe, ig its more complicated to model
What are u pursuing?
i have no fucking idea, maybe distro sys, im comp eng so i could do quant dev stuff, like people at the company im interning at went on to imc, hrt, headlands and shit, the pipeline is real, but ultimately if ur doing tech, i think u will be more valued in tech, i just like that in quant dev they seem to do real engineering
if u want to do fpga stuff, the quants will snatch u up, im not particalarly interested in fpga stuff. if u have really good c++ knoweldge u can do quant dev, i like c++ and have decent knowledge in it but there are significant flaws and i just dont think its worth it
like pay is comparable to faang, except u need to be just as qualified and there are way less positions
so its just harder for no benefit for quant dev
qr they get paid the big bucks but its also saturated af
thats the problem with good jobs, the people who have them wont shut up about them then the market gets saturated as everyone hops on the bandwagan looking to make ez cash, the ogs who were advertising their jobs are already seniors so the saturation effects them less, the new blood is getting aids
like pre 2008 would have been prime quant time, or even a little after 2008
not too many people knew about it so it was much easier to get a job
every time u buy stuff from your margin account or invest in mutual funds you’re essentially buying from them
I think absolutely the trading field is super depressing and you won’t be as valued as you are in big tech. I mean they’re only in the business of making money and nothing else but that’s the trade off to being the millionaire wallstreet nerd 😵💫
ya finance they dont value the eng boys as much, maybe hft since most people their are cs but in anything else ur kinda looked down upon
I think it builds grit, maybe start off HFT/MM couples years >> retire into Big Tech
I think HFT mostly deal with stocks by placing hella limit orders at certain prices and selling them in the blink of an eye
HFT make their profits from the underlying and not derivatives
Hold on 😂
Peak6 this summer
I confused myself i’m still learning
ty tho
Quant trading
I’m confused how do you price an equity? Is that not just buying/selling to make the stock move?
it takes .1 + seconds to blink your eyes
HFT trading is done at nanosecond latency ~
.1s = 1,000,000,000 nanosecs
Wait before you continue, you’re getting into options, i’m talking about the securities not the options
So pricing the security comes down to who has the most money cause you’re just buying up all the supply to create higher prices. No mathematical formulas right? (NOT options)
Wait do the opposite
can we switch
Wait how is that different from what I said
Apple has a prop firm 😭
i’m kidding
yeah I’m wondering even if they liquidated all their capital to buy apple would it even move the price significantly
probably not
What kind of operation do u think Tim Cook has to short circuit a theoretical price surge like that? @blissful kite
I trade every day
rip
Tim Cook has a prop firm for sure
They don’t sleep
Cause if Citsec decided to skyrocket apple overnight, how would Cook react fast enough to sell
Hehe
OTC 😵💫
Oh I believe it
phones? wdym
Oh what do u do?
r u a student?
😭 free tracy
right
seems trivial tho
Ye, that’s A LOT more exposure than most will ever
grats
mid but whatever
start somewhere
thank you
will do
is otc prestigious 🤔
Do quant devs earn more over 10 years amortized
Probably avoiding ultra sweaty 8 figure salaries
when u want to say average or total but want to impress the essay grader
how goes it
How is cboe / cme in the field, working as swe
amortized 💀
this guy is stuck in algos class
amortized means over time
amortized is redundant
as you said
(over) 10 years (time)
this is why ur at jane street and im at amazon
🥱
compared to qrs?
i thought there was more growth for qr compared to qd
He’s probably talking about compared to tech
i feel lke learning ocaml is just way too specialized
ocaml is kind of neat but I wouldnt use it again outside of the courses it was required in
Although its impossible for me to understand some of the ocaml code I write sometimes
I had to force myself to stop learning ocaml bc of how unproductive it was for getting a job, top 3 language tho
u go to harvard? idk any other college that uses ocaml lol
nah maryland
Theres a required class thats kind of an intro to automota theory and functional programming
Uses Ocaml for the majority of it
The compilers class also uses Ocaml (sometimes some other functional langs I think)
Ocaml is disgusting
lmao i like how most courses on that list are about programming languages and compilers, and boston college just has it for cs1
Anyone had exp recruiting new grad for qr without exp? from a decent school
man dont give up yet 😭
Too late
What do you think caused you not to get an interview? School prestige?
I got hella interviews
But for ng it’s a different story
yo
was it possible?
no
anyone hear back after point72 data eng. hackerrank / hirevue?
i think he ment internship
although i know a guy who got a job at hrt and helped one of my friends get a job at imc
although both are insanely cracked so that prob why he helped him
how much c++ would u need to know for quant dev?
do u guys think qd will transition to rust anytime soon or is that a pipe dream
i feel like finance is more boomer esque
genuinely what are the differences between like ocaml and haskell, how funky can u get with functional languages
i mean haskell seems really cool but im pretty sure its considered dead
whats the cursed question
this?
Yeah they asked me to obtain a complete system of C^\infty conjugation invariants for Morse-Smale diffeomorphisms
Anyone here is a swe at trading firms or QD, maybe 0-3 years , juniorish. Could I pm you with some questions please?
whats the meta -> quant pipeline? I wanna do a quant internship for my last yr. Which companies are easier targets?
lower quant firms are easy/have chill interviews but not better than big tech
I'll def need to step up my LC game.
are you expected to be able to solve most hards
or is like 50% ok
Which company?
i guess its good practice atleast
i was j wondering bc it's so late in the recruiting season
I mean if they reached out they probably have a couple spots
yea they said application still open but closing soon
I have heard for quant-dev that making a trading engine is a great project. But for quant-research what projects would you recommend. And would you recommend specific buy/sell side quant-research projects?
Even if they are non-finance ML applications?
that is not a side project lol
takes way more time to not be qualified as a side project
but sure
i think thats the point
does js "blacklist" if u fail the onsite?
They just decide you’re perma not a good fit?
citadel doesn’t blacklist right
im pretty sure it depends on the round u get to
onsite?
yeah on the onsite
like assuming i fail before lunch
for what round?
2nd phone
ya i did
first phone rlly easy
second phone was easy too but he asked me a mathy optimizated q
second phone is just 3 first phones bacl to back no?
that was very niche
it says that on the document they sent me
thats final bro
even tho they say its only one phone round
they give multiple most times
wait so they call it First Round Interview then theres Virtual Onsite and then thers Team Introduction
but you're saying theres multiple first round?
yea
fck
for most ppl ik including myself they gave us multiple of those
i think they have a lack of certain indication
what role?
swe
hmm ok
im swe as well
did u ask recruiter about it?
like why am I doing first round again?
no cuz my friends had to do that too
they just do that
so didnt ask
ik someone who had three inital phones
althought i heard three is rare
atmost two usually
and then its final which is three back to back phones p much
interesting
I guess if they didnt get a strong enough signal?
but after final
is team introduction
yea
I assume you mean mathy leetcode style? or just a straight math question?
yea bruh those the worst
like hard math ones
not the basic algebra ones on neetcode
wait deadass/
like for intern or intern + ng
i think they hired a few
or what if i just run intern
hard math ones are the best to do tf
its always binary representation
or do sqrt of big number and find smth
less rounds for swe and if ur not perfect ur gone for js
👎
the dude asked me some combo thing
good for u buddy
Lol that sounds brutal
i wish it was that



hoping I dont get one
