what company
ah yes
Burger King
bruh its not even a company, its a uk institution
o damn

royal guard?
ye its a position at a uk government institution but its nothing cool lol
stop describing my job
do they have good wlb

just web dev
no.
free food at the job is god tier
WHAT
wait fr
Amazon has free bananas
GTFO
brooooooooooooooooooo
free coffee
bruh this is news to me
That’s why chick fil a on top
free banana is good
no free meals
i hear the bananas at amazon are pog tho
nah this is an office standard 
Microsoft has free drinks but we only have subsidized food
sap is like a fraction of amzn and they give free food
so like 50-75% discount
anyone recently solved a question on codesignal related to counting submatrices containing 0s and 1s?
the free meals went to the inflated paycheck at Amazon
I hear that MSFT in california has free food

bruh thats dp right there
they got baristas and everything
i swear it is, i seen an lc with that

doesnt sound like dp
the grid is abstract
oooooooooooooooooooh
the problem is like:
You are given an abstract grid of 0s and 1s and a list of coordinates representing 1s in the abstract grid.
You need to find the occurences of each possible counts of 1s of 2x2 submatrices in the grid
bfs
it's not bfs
it is not
this
bruh i been looking loool
ye nah its not the same
the ones in your grid
kinda similar tho
brute force and go from there

LOOOOOL i tried the lc one and ngl i was hella confused 
ye thats what i was thinking about
you need to find the number of 2x2 submatrices containing 0 one, 1 one, 2 ones, 3 ones, 4 ones
so
brute force
ye in theory u could brute force i guess and for each 2x2 check if it meets the requirements
def feels like dp to me
it's only 2x2
only 2x2?
brute force that baby
wdym by bruteforce? create the 2d grid. It would TLE for sure
sliding window yeah
well
is a matrix sliding window
a kernel 
im a machine learning intern now
im using big words
prob like 150
you're a big boy
@gentle latch what's the TC like for FB return offer
you need to find the number of 2x2 submatrices containing 0 one, 1 one, ..., 4 ones
array of length 5
ngl this on a codesignal is kinda rough especially when speed is really important
yeah this is some headass luck
fr i be praying for this weekend imma try the SIG one

whats GCA, sorry i have no idea what this is
sig is not codesginal
nice
General Coding Assessment, 4 random questions from codesignal bank
sig is 2 or 3 questions
oooooooooh thats interesting i didn't know there was a difference
thanks for the heads up
bruh i wish i was in this server, this time last year, bruh i was such a noob

I tried putting all my coordinates in a hashmap and compute the occurences in a smart way. I probably messed up in the implementation. My solution was like 70+ loc
written in ts
yes
coordinates = [[0, 0], [1, 0], [0, 1]]
yes it will
mr juda
help me

What is greatly exceeds
mr Juda, I need you
I got smashed by q4 on codesignal
Yes that's what I did, hashset no hashmap
it's done
I'm not cheating
I only used 1 set
ig im delusional
well yeah other then trading firms
wait
anyway, I accept the L
well I mean yeah its js
in terms of tech companies I dont think it goes over 200k base NG
only HFTs
thats got to be cap
Yes, that's what I also did
maybe
jane street please chupapi 
Idk
complexity should be O(C) where c is the number of coordinates
why log?
I'm sure you don't need to sort
I swear, every time I open this channel, I get a small anxiety attack, lmao.
“What is everyone talking about”
“Wtf, I don’t know this”
“Fuck, I’m so behind. I’m so screwed”
lmfao so true
let's say your currentCoordinate == [rowIndex, colIndex], you can compute the 4 submatrices containing rowIndex and colIndex with +1 or -1
I know that, but there is a way to avoid counting duplicates
basically
I'm not that dumb
you consider top and bottom sumatrices
you count only top submatrices where the numberOfOnes == 1
you count bottom submatrices normal way
4 for every row, col (topLeft, topRight, bottomLeft, bottomRight)
yeah
You don't count top submatrices where the number of ones is != 1
we only care about 2x2
not 9x9
you also do boundary check
my general idea was to compute 4 submatrices (or less for coordinates on borders)
[[1, 1, 1],
[1, 1, 1],
[1, 1, 1]]
the output should be [0, 0, 0, 0, 4]
only 4 2x2 sumbatrices are valid
I considered every 4 corners
but I see my mistake now
basically when rowIndex == 1 || colIndex == 1 || rowIndex == numberOfRows - 2 || colIndex == numberOfColumns-1, you need to consider top submatrices. I forgot this case 
it took me 70-80+ loc
so not ez for implementation
and conceptually, I don't find it ez neither
it's not like q1, q2
Got the Lyft ETA certificate, gonna print and hang it on my wall 
Does anyone have insight into how much TC Palantir gave it's new hires this year ?
would it work for this case @woven quest ?
I'm not sure to follow you
i didnt get anything
I think it will not work.
Consider:
[[0, 0, 0],
[0, 1, 0],
[0, 0, 0]]
it should return [0, 4, 0, 0, 0]
whati svery easy
like lc easy?
LC easy, LC easy, LC medium
LC easy, LC easy, LC medium
LC easy, LC easy, LC medium
LC easy, LC easy, LC medium
LC easy, LC easy, LC medium
lyft eta certificate
you said: consider each coordinate as the bottom right corner
that's why you need to compute all 4 submatrices
amazon got me fuming right now
anyway, I hope no one here will get that q4 again
i sent their scheduling form with an incorrect date on it and i immediately sent an email to their help email asking that the date be disregarded
i got my interview confirmation and it’s that date
so now i have an amazon interview in the middle of my c1 final
?
no worries
i might be able to ask them to give me the one hour break an hour in
I iterated 2 times, 1 time for building hashset and 1 for computing the 4 submatrices
true ig
I didn't
to avoid duplicates, I tried doing the top bottom approach
I now see where is my mistake in the deduplication part
alzheimer like me mr juster 

yers
I need to rest with my discussion with @woven quest

Hi
🤓
Did anyone that applied to imc with the old link get an oa
HELP
I NEED TO GRIND
@hearty river
i need to ramp up to 5 leetcode problems a day
currently at 1 
bro been on -5 problems for 3 weeks. I am loosing braincells
How do y’all do more than 1 medium a day
It takes me a solid hour to come up with some solution to a medium
Like how long do you give yourself to work on a problem before looking at the solution
15 minutes for me
20-30
add?
idek bruh
5
is that bad
give urself some time to fully dissect the problem bruh
i think 5 seconds is plenty time
no i meant seconds oops

Ah gotcha gotcha
Yeah, you can forget about that Jane Street internship. Too slow
bro fuck koko is eating bananas this problem is killing me
amazon is making me lose braincells
can we just get handed internships like it was in the 60s
i feel like im getting nowhere with leetcode and i've solved almost half of neetcode's list 
how long does amazon take to email back interview time from final survey?
ayo 😭
What are y’all’s responses to or good responses for “tell me about your biggest weakness”. My usual format is to tell the weakness and then explain how I am progressively working on it.
Yes
Yes
how do you prep for amazon final
leetcode lol
Amazon tagged/b75 + behavioral prep
i’ve literally done only like 30 lc easy qs lol
Seriously tho this is what I do, or like explain a time I failed because of a weakness but explain what I learned etc
HRT application opened, anyone have experience interviewing there?
is it just leetcode?
how was the Optiver OA
How long does Jane Street take to get back to you? Applied July 24 w no word yet
F
I thought they reject pretty fast
How tf do you have time to grind w/ all the other stuff in life
study codeforces
Like, I come home from work, meal prep, clean up, and I’m already pooped
hmm, good point
i should just eat ramen and frozen foods
Same i come home at 530 and then i eat dinner and some youtube and im like alr dead tired to leetcode
Just grind like 10hr of Lc in the weekend
Lc at work
Bruh i do that but i’m scared if coworkers come up to me and see my Leetcode tab if i forget to close it
i did that for a bit but I realized that with half of my mind trying to figure out the lc problem, I start to fall behind
i'm too stupid to multithread
jpm chase oa auto?
imc?
'Moved to another job' is offer? amazon
Post ss
yeah usually
let's goooo.
when did u take final?
29th July
wait shit I forgot to finish my cisco meraki application that I started a while back
is it too late?
i mean, it's not rejected
its probably an offer


Congrats homie!
congrats! Out of curiosity, when did you apply? Just wanna confirm that I'm already autorejected and ghosted lol
hard
very hard
80in8 is tough but rest are tougher
i can dm u more details
hey sure
added ya
oh thats fucked up
what they ask in interviews i never been to quan interviews
what difficulty level are those generally?
hard
which position
but the rest of the process is hard asf
swe oa?
swe
it def wasnt easy
i already know quant is gonna be hard
but it wasnt hard
it was vague
it was just a bitch to code
thats the only problem
yeah
lot of my friends were complaining about vagunes
so just dont overthink swe, otherwise youll spend like 5 hours thinking on it
ah i applied for both and got quant lmfao
man, I'm so nervous lol
this is what held me back last year. like the fear of fucking up the coding interview
that and no one would speak to freshmen unless you were a god lmao
think of it as an opportunity to show ur talent ig
instead of a test
you got this bro
i believe in you
yea thats all any of us can do
yep
i think he meant for summer 2022
Applied around July 1st week.
When did you get the OA invite?
Web algo engineer
Received the oa on codesignal
Solved the 3 questions
Received the L the day after I completed the OA

Anybody got invitation for Akuna C# final?
Does anybody know what kind of questions to expect for it
We not as smart as you

C hashtag
my inbox is so empty 
can someone send me their offer email to give me a dopamine boost
in bezos' armpit
where's ur imc oa?
in Scott Ihrig's armpit
Where’s ur HRT OA
i just applied
is it auto?
i applied for c++ so hopefully they don't resume reject
issue is that i don't have any c++ experience on my resume
i've only done c++ for leetcode and cp
How did you learn cpp
it's pretty similar to other languages
Idk cpp nor python enough to apply to HRT
apply anyway
apply c++ bc the application says they have more spots for c++
you'll have to do the oa in c++ tho
Latest useful tool for converting java code to equivalent c++ code, With free and unlimited requests to all users
i have no clue how good this is lol
Ok I’ll use that during interview
std::vexorstd::string
cause you're gonna write line by line using that
and who tf writes code line by line without going back and forth
i don't have STDs
I just need to memorize the methods for the data structures
Do you think the interviewer will let me google them
if they test stuff like templates im screwed
i haven't used templates enough
anyway this won't be a problem bc ill get resume rejected
undefined behavior
aka C++ specs don't define how it should be dealt with and it's up to the compiler
which is bad
it could also just mean it's nondeterministic
like reading junk memory
No
probably not
im a tech lead at js and it's been a long time since i've done interviews
Do they ask LC shards
i've heard it's mediums
I've heard HRT core dev (c++) has very little growth. Gotta be either algo eng or algo dev to get the big bonuses
that seems kinda slow
I can do it fast if I’ve seen the problem
a medium shouldn't take more than 10 minutes
whats hrt process
Is it even worth applying for swe internships at trading firms without any OS/distributed systems knowledge
There are python teams at HRT mostly focused on data pipelines and research infra
i got through Python Development final at Akuna without OS/distributed system stuff
where is my imc auto oa :waz:
haven't gotten result yet though
But for C++ theyre definitely gona ask right ?
Idk python well enough and im better at cpp but i have no os coursework/knowledge sad
Yea for C++ expect a lot of OS intricacies
Algo dev is probability and stats
Algo eng, not sure. Dk if SWE - Python is algo Eng too
HRT’s OS qs are very basic stuff you should’ve learned in your OS course
They also have systems eng which is just python and devops
this assumes your uni has a good os course that isn't taught by a parrot
U think its possible to self study or nah
Lots of uni’s systems courses are available online to self-study
CS61C for berk, there’s the CMU one, ECE 252 and ECE 350 from Waterloo if you wanna take a look at what I studied 
waterloo one is written in canadian tho
It used to be combined for us too, but they split it so they could dive into each a bit more
yes
I like cats
los gatos
el gatito
I loved Scratch
meow
when can we do OA in scratch
bruh
anyone apply imc with (dec) 2023 grad and get oa?
I plan on graduating Dec 2023 but I put May 2024 bc I don’t want recruiters to see 2023 and think I’m looking for new grad
is 843 codesignal good?
also some companies ask for just the year for some reason
yes
roblox is just the generic one
🤫
how would one do so
asking for a friend
😆
is the score also time weighted?
Yes
does Cisco put you on cooldown even if you aced the previous OA?
nah it doesnt
i got 837 with 5 mins left 
lol i kinda bombed the cognitive
will it fuck me
yes
oh damn wtf
i had like 25 left got 843
wth
ehhh would like it to be stronger
probably
i got some dumb q3
sigh
i believe its normalized yes
its definitely normalized
is roblox known to have a difficult process
r u sure
could it be based on time/space used?
or na
then why does 300 for all 4 yield diff results than expected after factoring time
is it time spent in IDE?
or time spent open
ok
SAME
ill take it again anyway
im hoping that all 4 should be enough for 2s and roblox
i looked at the app again and i accidentally chose dec 2022 through the calendar ui
roblox pays good tho
Is HRT OA auto?
So what exactly do Roblox SWE do
Like I would assume they got game developers
Exactly lol
No idea
Basically roblox
wait really???
Isnt it literally roblox
U go into diffeernt worlds or some shit with the same character
Yes
I mean ig
Exactly 💀
Meta acc 😳
They trolled my stocks price is what they did
Yea only did that
Was paper trading before
To much work
Most of the time u can’t beat it
pretty much yea
last year it was mid august early september, this year it kinda started late-ish july
so metaverse is just vrchat
so intern apps have already started closing??
Which ones
nah i was asking, im new to this and im not entirely sure when applications are opening/closing
I see. I noticed a few got closed on the PittCSC repo but the only big one afaik is Salesforce
Hopefully that one opens again 💀
idec if it opens or not cuz ik im not getting in LMFAO

i havent even finished my DSA course yet
this is the earliest of the earliest ones
thats very reassuring
I heard they closed it for Futureforce conference but that they might open it again soon?
Since they were busy hiring people from there
I didn't apply since I didn't know they were gonna close it down within a couple days
Trying to apply for Nordstrom internship and the only "How Did You Hear About Us" options are campus, job fair, and referral 
i have to start grinding like crazy
handle it broski
my dsa summer course gonna end in a couple days
and then gotta do some extra dsa shit to really lock it down
oh that's cool - keeping it fresh in ur head
yessir
good luck
is it feasible to get an internship with HRT, optiver and stuff with basic software engineer skills? or are they looking for a specific skillset
anyone know when capital one reaches out after the codesignal?
like 3 weeks for me
did anyone get the predict infecting deer roblox oa
burh i didnt know there was just 2 tasks
soi tried speedrunning
and finished 20 min early
fml
how much does the roblox gameplay matter lmao
im trying to play roblox and get good at it
or alright
im set for the coding but i don't wanna get fucked because i can't play roblox 💀
🤣
ye
i fucked up section 1
section 2 was ok
i did this before taking a dsa course
this what i used
not most ideal bc in JS (u should lc in python) but i found it great otherwise
why are you doing C++?
L
i do it in cpp and its fine
Like its not that different
i mean sure it takes a bit longer
even in python vs js there's a big difference
imo python helps u do a lot of things
and thus becomes very helpful for leetcode
example u can compare two arrays or dictionaries with equal operators
you have things like .isalnum()
easy reverses like [::-1]
ye that's why python is goated
super quick syntax for things like for num in nums:
i think this is all in cpp standard libraries ngl
yeah i'm not sure
ik they werent in js
i mean u have that in most langaugs like cpp its just
for(auto n : nums):
i also haven't tried doing leetcode much and C++ i've only done C++ in uni and never even seen that for loop structure so take it w a grain of salt
python is better for annoying string parsing questions
yeah its fine i do c++ too, but when i started i did python
also for c++ you can trick the interviewer
to get people to drop out
just python doesn't make u think ab as many things
and as a follow up change your code to be templated so that everything is done at compile time
learning C++ made me consider way more ab the code i'm writing
i woulda never had that in python
and tbh woulda been a bigger noob
even doing Java now is like oh dope less to worry ab
but i appreciated learning C++
bruh python was confusing to me cuz idk if things are passed by reference or by value and like the idea of most things like strings in python being immutable seems so ineffcieint
yeah i feel u
pass by reference doesn't really exist in python
besides arrays or dicts etc
u cant "&" something in the param
it'll always be by value
there are a lot of times where that becomes aids and i wish i could pass by ref
For capital one, do we just apply to the McLean location, even if we dont want to be in McLean?
bay area sounds cool unless I'm paying my own rent 😔
But working a side part time job during college to do that has taken away time that could be spent for Leetcode. Working 1 1/2jobs during the summer to do that has take away time that could be used for Leetcode
Bay Area is cool but the actual bay is underwhelming
idgaf about the bay i just want good boba and diverse food 😔
Lol and industrial area
Maybe closer to the coast itself you’ll get that
i don't fw the bay much
i live in LA
and isn't full of techbros
people in LA are much less competitive and more down to earth from my personal experience w/ the bay
true
the retirement community thing is just based on which part of LA - idt that's really much of an issue
@stark basin are u also from LA?
I'm in Irvine
fire
so 40 minutes away from LA
Seaside nights 🔥
emerald bay beach in Laguna --> Cliff for taco tuesdays are top tier summer vibes

Python or C++

the detect fraud thing?
yeah it's pretty fucky
how many test cases did you fail in the end
I hate akuna
you'll probably get phone then
i failed 1 and I have ZERO clue wtf was wrong
got phone
is it leetcode sorta stuff?
everyone else I've heard who did it failed 1 test case too

what

so, just implementation?
ew
they push the OOP aspect hard
some OOP questions on the phone and then half of the final interview was OOP as well
the datetime

i will say
leetcode didn't prepare me for Akuna interview
courses and just regular old everyday programming projects did
none of that
o ic, it's basically an ap csa test 💀
AP CSP is useless
i took AP CS A, got the 5, and then somehow forgot every single bit of Java except for "System.out.println"

I just remember something about a Scanner
colleges don't give a shit about APs
but it sure is nice skipping class prereqs if your school allows them
taking Calc BC saved me like 4 courses
CS A saved me 2
by credit yeah
UCR is quarter too right
yup
not long enough for a winter internship then
we only get like
10 days winter break

you get like 2 weeks between fall and winter, 10 days between winter and spring
and then just a long fucking summer
still prefer quarter cause you get to take more variety of classes
for the codesignal are we allowed to search for help while taking it
Syntax stuff yeah
Where’s my IMC OA 
@gentle latch how to become mod
I want to ban ppl I don’t like

Kinda sus 
How “nice”
I’m a jojo fan
reeeee just finished my intern presentation
Aaaaand they did!
They literally invaded Taiwan coast
And people taking sides like it’s a football match

apple sobbing rn
is snap open?
no
What was Roblox OA like
lc imposible
Bruh rly
No I did rly bad lol
Roblox wants like 840+ right
So essentially they want a perfect score
how do u know?
A lot of people say that Roblox needs 840+
Isn’t 840+ essentially like you perfectly solved everything fairly quickly
nah
you probably need all 4
but they resume review like jump man said
All 4 is 840 tho right?
No
All 4 is 830 and above
gca?
gca all 4 is 840
has to be custom right
What if you get 840+ and have a shit resume
it says "around"
someone on reddit said they like lower scores but goated resumes, idk how tru that is
GG
apparently not
Prolly late here but how was Amazon OA
any idea when salesforce will start processing the intern app ?
Mine were very easy questions. A 2 pointer and a hashmap question
same
what is salesforce?
speed: 0
Nah I think I could have been slightly faster lol
But it's alright
Even if you pass everything 100%?
Dang
Can't imagine how to get 850 then lmfao
Typing contest
they aren't?
@uneven sand
Mine was definitely auto
I got it literally 15 seconds after applying
unless there's some cracked recruiter
well were they a rising sophomore
I mean grad year check is still auto id say
tell me why 810 sounds worse than 760 by that description
can confirm
Ikr
lol 760 is "can develop large scale apps" and 810 is "can implement ideas that don't take too much coding"
Yea but q4 is much harder
true
Always go 4th
how long should you attempt q3 for
like I know don't write code til you have the solution in your mind
but lets say you're done with q1,2,4 in 25 min
Honestly don’t matter finish 4th
no I'm saying
if you get 1,2,4 done
and its only been 20 min or so
do you spend 15 min on q 3 trying it
or just skip it
fml
ofc
man I have a recruiter call w them next wednesday
not interview tho
do you think they'd give me a diff interview process if I said something like "I aint the best at algo trivia stuff but I can build real applications well"
lmao
I was thinking this too read it somewhere
But from what I gathered
Might aswell try
yeah true
I know you shouldn't run test cases unless you're confident
because it deducts points for missed tc's
Cuz like I did practice tests and did that
but doesn't score the tc's if you don't do the q
But made not too much diff
god dude fuck the interview process
really making us fuckin exploit hunt like its destiny 2 or something
Ong
Gonna upload a video next year
"FAANG SPEEDRUN WORLD RECORD - 3 DAYS 12 HOURS AND 36 MINUTES"
schedule all my interviews for that tiny time period
Why do I feel like that would give u a higher chance
does anyone have amazon recruiter info for interview scheduling purposes
if so pls dm i need to speak to a human lol
No way lmfao
does karat do behavioral
What company
intuit
no
Bruh .-.
What was your question 4 dam
it was like some lightpost with boxes
Idk if anyones seen that before
It was so retarded
And I Tled on a bunch of test cases
min light post needed to cover some number of points
Oh
I’ve seen that before
Is optiver OA auto
ye
How bad was it
Has anyone done Citadel’s hackerrank assessment? How was it?
I flopped it got 2 hard 😭
Rejected
Did 1 question all test cases but other one was GGs
RNG was not on my side that day
citadel oa is auto
Yea
they do resume screen after oa
Yes fs
so i passed all the tests and still got rejected
Bro u sounds good at LC but ur resume holding u back
Usually it the other way around
🤷♀️ 😭
Did u update it after
no
Bruh
2 mediums I think
just do it with no expectations cuz u get screened out after anyways
