I'm not sure what FB is looking for
stark crypt
Facebook “officially” open
@tired bay wtf i applied 2 weeks back. do I apply again ?
bold gull
They were trying to get input for new interview questions for Roblox and i guess the employees picked the super difficult ones. If u can make it through the OA though (btw you dont need to get a perfect score) its such a great company to work for
digital carbon
I'm not sure what FB is looking for
@dark jewel I'd guess that they've shifted recruiting goals around rather having a higher bar than usual. like their bar is high anyways so I doubt that has changed.
near finch
I connected w a FB recruiter via a Latinos in Tech group on fb and she told me new grad hiring will be v competitive and limited this szn due to covid
Has anyone here ever interviewed with Disney? (Specifically for ESPN and Disney+ Streaming)
dark jewel
idk how high the bar is though. Had a friend with 2x citadel internships and an HRT internship get autorejected by FB with referral also
near finch
That probably shows how limited it is this season @dark jewel
Who knows what hiring looks like, so many people get referrals nowadays, I’m sure they’re being extra picky right now
hoary pewter
@tepid minnow yes a friend got something similar
digital carbon
@dark jewel was that this year?
dark jewel
yeah, was like three weeks ago
digital carbon
interesting, yea I got no clue lol
off-topic, but I'm kinda surprised how much people want to work for FB
dark jewel
i think it's less facebook as a product and more about how much they pay
FB has the highest liquid new grad offers outside of quant firms
digital carbon
true, their packages are certainly top of the line for tech (from what I've heard)
tired bay
Hopefully Amazon Chime doesn’t crash for interview cause that platform sucks lowkey 🤦♂️

@pseudo wigeon sounds pretty late, I think they usually stop giving out offers early November. I've heard of cases where they cancel people's final round interviews because all the spots fill up. You might want to schedule the phone interview earlier.

For those who scored +800 on codesignal, how many questions did you solve and did you pass all cases?
warm stone
I sovled 3, 820
worthy spear
I usually go in order 1,2,3. Am gonna try 1,2,4 this time
sleek coyote
Just took 1 codesignal, so I dont really remember. Can you just solve 1,2,3 and exit the test for a higher score?
worthy spear
I believe so. Last year I solved first question, then moved to second. I lost my connection in the 2nd, so when I came back to it I got 710 for solving first question only
So i think that might work
pseudo wigeon
from what i understand codesignal only takes into account time for fully solved problems
so if you solve 1/2/3 and partially solve 4, they don't factor in the time for 4 for speed score
hoary pewter
my msft recruiter told me they were starting first round interviews last week, so I doubt most people will be waiting until february to hear

On the contrary, if I take things one at a time and try to focus on that one thing (for instance, a coding round), I tend to perform better
worthy spear
Have you guys been getting ghosted mid process? I had a few companies that say yeah let’s schedule interviews after hr call and just don’t??
It’s really weird
tepid minnow
In my experience it's not always ghosting, sometimes some companies reach out to you towards the end of the cycle as well so try and be positive
worthy spear
No like I emailed a month later and they were just like yeah sorry not hiring currently even tho we were doing their new grad process
Not just end of cycle stuff. It’s like a rejection before even interviewing
hoary pewter
AT&T ghosted me after like 4 interviews, I went and asked their regional hiring manager at a career fair what was up and he was horrified that it had happened and that id interviewed that many times and he had never heard anything
he restarted the process
so sometimes its just a mis communication internally or something

@nova maple yeah it just depends on the company ofc.

wait how does codesignal scores work?
like if i take a certified assessment before anyone has sent me a codingsignals score
can i send that score in to the companies, or do i need to take their specific test?
gusty citrus
@astral garnet how long did it take for you to hear back from bloomberg from final to offer?
modern belfry
it's a general coding assessment
i took robin hood's like last week
and since there's a cool down of 2 weeks between each test i could share the results of my robin hood assessment w/ ebay and databricks @dark jewel
dark jewel
so if i take a general assessment before anyone sends me a code signals link, i could send my general assessment score to them instead of taking their coding challenge?
modern belfry
yeah
dark jewel
and scores only last for 2 weeks?
modern belfry
no like
you can take the test again after 2 weeks
you can only take the test once every two weeks
modern belfry
i think that depends on the company some will have proctor setttings on while others don't
I had to take a picture of my id
and have cam and microphone and screen sharing on
dark jewel
so if i take one that doesn't have the stringent proctor requirements, then a new company wants the ID, mic and screen sharing on, i'd have to wait 2 weeks to take another one?
dark jewel
but would it get accepted by that company?
or do they want another one done that has thee mic/id/screen sharing?

@latent cipher uhh kinda both? I had to pick a date and time and then they asked me several questions like ranking the preferred location, but it was not required, so I just answered required questions like expected graduation date and etc...
digital carbon
@native ruin fwiw optiver gives 72 hours because they recognize that no one ever needs to code under pressure, nkt because the OA is uber difficult. Someone else on this channel said it wasn't too bad iirc.
pallid pilot
@viscid zenith I think there was 9 questions in total, some short answer (type and explain), some multiple choice, one SQL question, 2 coding questions (definetly LC easy-type) and then a large 2-part API design question

latest as in further from todaay

hard to tell without more context
tidal hazel
maybe your availability was like, not in the window of theirs?
digital carbon
I'd say a red flag would be you giving availability and then the recruiter ghosting
If they scheduled an interview then I don't see an obvious red flag, probably just low interviewer availability

Thank you for your interest in DoorDash and for taking time to apply to our Software Engineer, New Grad position. You have a strong background, but after reviewing for the role, we have decided to not move forward at this time. If you have applied for other roles, you may still be under consideration for those roles.
Is this an automated mail or do i have a strong background?

@tribal timber Sorry for late reply, I applied Aug 28th
As for getting replies I had a Google internship this past summer so that's the only reason why tbh
I think other people who are getting OA (or phone) that aren't mass send OA could also share what they think makes them receive OA
Oh I also submitted my resume to Grace Hopper resume database and applied thru the links they send in emails occasionally
That is how I applied to Qualtrics and I got phone
the links are often just regular job posting and not a link specific to Grace Hopper so IDK if it makes difference

i think google is the worst suspect for taking forever. i was looped for 6 months for an internship

So many front end tools literally abstract away the harder parts of the front end so I get the script kiddie comment kinda, but I don't see the problem with using tools?

nova gyro
kinda confusing to say you are inserting them
its like creating a heap out of an array
worthy spear
yes correct. heapifying is o(n)
lilac rose
I remember someone saying it's o(n) because.. something about half of the elements on the bottom level that does not require percolation
worthy spear
but that would just make it n/2 log n
logicaly
theres some weird series proof for o(n)
lilac rose
n log n is if you do log n insertions n times
nova gyro
what if it was just a rumor that heapifying was O(n)
lilac rose
heapify is something different
nova gyro
but none of us smart enough to disprove it
lilac rose
:galaxybrain:
nova gyro
b/c i definitely didnt understand it when it was proved in class
maybe some brogrammer just posted it on showerthoughts one day
nova gyro
its a bit different cause the heap is not really sorted
worthy spear
idk about worst case honestly. nor the innerworkings of heapify.
last linden
but quicksort is n^2 worst
worthy spear
i mean just in general you can insert n elements in n. idk if that is worst case or average
im not smart enough to argue it
nova gyro
the heap is not sorted though
it just obeys the heap property
and to take things out, you need log n each time
prime ibex
"heap properties" I like it
stable plume
Yeah creating a max heap is just inserting the elements into the heap portion of the array (which can be done in place) which is just adding to the end and then moving the element up to correct its position
It would then be nlogn
Since you have to do it for every element
worthy spear
but you dont have n elements at every move
so tis not that simple which is why it isnt nlogn
mystic vortex
Is there a server for interview questions? Sorry im new to this
stable plume
and m is the size of the heap portion
prime ibex
I need to learn how heaps work.
stable plume
But the m will eventually become n
prime ibex
I thought it was the same implementation as a sorted set
(Fun fact sorted set is really a treeset in java)
worthy spear
heaps are knockoff sorted
stable plume
So the way it works is an array representation, you tell the left and right nodes by a formula based on your current index
And can tell the parent node the same way
worthy spear
highkey recommend interviewcake
for data structures
its cheap rn
or just go TA a data structures course and youre forced to learn

LC also has too many try hards. No I don't need DP because we can use DP if it is the same time complexity

also theres a lot of solutions you shouldnt give in an interview

Dp is caching

yes so recursion + avoiding repeat work with a cache
hoary pewter
ya, we learned the key idea being that it is a way to express your solution in terms of a polynomial number of sub problems, that you order to avoid recomputation

top down is not the only approach
if you're struggling with dp I'd advise you to look into the theory first, before diving into "leetcode" patterns
wind acorn
tysm all for the dp resources
stable plume
BTW I practice bottom up DP in this way:
- Find the recursive solution
- Identify which variable(s) are changing in recursive calls
- Make a DP solution matrix by hand using a sample problem with the x (and possibly y or even z axis) filled out with the variables that are changing
- Analyze the matrix for how you could iteratively recreate it, the steps should match the recursive calls (if you use max of two calls, you should be using max of two values)

dp solutions are generally very cryptic and do not convey the the intuition

Yes by recursive solution I just mean figure out what the recurrence relation is, definitely don't write it all out if you want to reach DP code solution!!

Seriously following those steps you can always reach bottom up DP, the trick is doing it fast enough LOL
And being comfortable with recursion of course
languid plaza
I mean vast majority of the time it is brute force + memoization
prime ibex
DFS, BFS, Two Pointer Problems. All have a template to them, very intuitive. DP is almost always exploiting some condition of the problem to cache

And that condition is the result of a bunch of research
You can identify it when written but there is not a template to write DP
@random knot Get what I'm saying?
random knot
eh not really
hoary pewter
tricky things can come up with DP too, like space limitations that require you to do things differently
random knot
dp as a technique is always the same
finding the recurrence relation is problem specific hower
this can be very easy, or very hard
same as any other problem
hoary pewter
we studied a longest common subsequence algo in school that you need to do with DP and divide and conqure to optimize space
and it was pretty confusing at the time
prime ibex
Hmm maybe I'm LC bias but finding those DP relations are much harder IMO then other algos
arctic drift
DP relations are just "harder" to find just because recursion is an iffy topic with a lot of people
Going from recursion -> DP isn't so bad
random knot
yea but like some are trivial
loud anchor
idk
arctic drift
you just hardcode base cases and go up from there
random knot
like coin change
prime ibex
and Fibonacci
hoary pewter
our prof used interval scheduling
and billboard placement
which I thought made total sense
hoary pewter
its because you do the ordering through a greedy selection
prime ibex
Probably because people just see Dijkstra as its own algo
random knot
it is?
rigid elbow
Dijkstra being dp makes total sense when you hear it but i guess many learn it separately so doesn't come intuitively
prime ibex

random knot
dp exploits optimal substructure
prime ibex
@random knot What @rigid elbow said
hoary pewter
you typically learn dijkstras when you go over greedy algos
since dijkstras does its ordering with greedy selection
prime ibex
So many knapsack lookalikes too

I really think you guys should try the technique of IDing the variables that are changing when you do recursion and then building the DP by hand
It really helped me, we never learned DP in school (or even hash maps... I go to a clown college) and I was able to solve the longest common subsequence problem doing that on my own
stable plume
Ah yeah I basically did the 2d ones as a challenge to learn the concepts and just take 5 million years until I get it down lol now I'm working on being fast
prime ibex
I feel like it is really easy to just try and go for the DP solution
Since you know recursion wont satisfy the time limit
but that really is the good approach
random knot
Before I write any code I open up a text editor and try to come up with the relation and base cases
stable plume
I looked at the subsequence one, I jumped into doing this once I figured out the recursive algo:
// Dynamic Programming
// f 1 2 3
// e 1 2 2
// d 1 1 1
// c 0 0 0
// b 0 0 0
// a 0 0 0
// d e f
then the implementation is easy
stable plume
And then I was able to write the DP solution
stable plume
Here's the recursive algo I wrote down:
// Recursive algorithm
// If either text is empty return 0;
// If text1[0] == text2[0] then return 1 + recurr(text1[1..n], text2[1..n])
// Else return max(recurr(text1[1..n], text2), recurr(text1, text2[1..n]))
Then from that matrix + looking at the relation I found out the DP algo:
// loop i 0 to max, loop j 0 to max
// Carry over max value from i-1 or j-1
// If the current letters are equivalent, add 1 to value
// return dp[max][max]
Apologies I wrote it for myself so it's probably just gibberish lol
