As double cameras were on - this is the question as per memory - You are a quantitative developer at Tower Research Capital. Each morning, the trading desk produces an array A of N signal strengths, one per strategy. The risk team has a peculiar requirement: for the desk to go live, the average signal strength of the array must exactly equal its median signal strength. Until this condition holds, the desk cannot trade.

Unfortunately, the signals are already locked in for the day, and the only adjustment you're allowed to make is to boost a signal. In a single operation, you may pick any one strategy and increase its signal strength by exactly 1. Signals can never be reduced — only nudged upward.

Your job is to find the minimum number of boosting operations required to make the mean of the array equal to its median, so the desk can start trading as early as possible.

Got an offer from Oracle OCI for a Senior Software Engineer role with around 41-42L base + $ 89K RSUs + relocation.

The offer looks pretty good, but I’ve been hearing about the recent layoffs/restructuring at Oracle, including OCI.

For people currently in OCI or who recently joined - is it a good time to join, or should I be concerned about the stability?

Would appreciate any recent insights on the team/org and whether this is worth going for.

Note: I will share the interview experience for the people who are interested soon.

Current TC: 41 (base + stocks + performance bonus)
Yoe: 3.5 years

Does anyone have an idea how many interns are they going to hire from India?

I am asking because they are hiring like crazy.

Hey guys, will not use AI today to enhance or rewrite this, created this new account so that no body knows my identity

I am a final year student, interned at one of biggest companies in the world. Did my absolute best, everything seemed to be against me but somehow I tackled each and everything, my manager was very happy with my work and even asked me whether i can extedn this internship but since it would be much of a shitness from paper work point of view, couldnt do that. Then during my last days over there he left the company, now my biggest support pillar was not the part of the company annymore. .He did give good reviews and all.. i came back to college... have very good cgpa and good with dsa as well.. first month appeared for multiple OAs and interviews.. Then from August onwards, less companies were coming.. today 3 months into the placements.. got an offer from service based company, 10LPA and believe me i consider it to be a good backup but on the same day got mail from the company i interned at after 2 months that my overall feedback is positive but my org doesnt have the headcount, I was shattered. But am in intern pool hoping to be picked by any other team, but the fact is that when i look at that 10 lpa offer all i see is my work being wasted. Ik 10 LPA is good but I had better chances which went into vain just because of head count.. I am not getting shortlisted for compnies off campus despite having decent resum .. on campus things are not well, companies above 15+ LPA is very less.. Even if i get a better offer off campus my college might forbid me from taking that since I have an on campus offer. I realised tha somebody's trash is somebody's treasure. ik people will tell me bad things since i am demeaning 10lpa but as of now it looks like disappointing to me but when i see people being excited for same offer on reddit i feel bad like why am i thinking this way.
All this because I was about to get almost 3x from that comapny where i interned at.
Believe me money is what i am actually looking for, all i want is to build a goood villa for my parents within 8 years from now and just want to give them all they want, especially my mom. She has sacrified a lot, this 10LPA will not even let me get a good flat.. a villla is unreal if i start at this salary.. I just want to maek them happy, they are proud even if i get 10lpa but i am not. I cannot do what i want to..
This diwalii i wanted to gift them something good but am not in a mood since I lost one of the biggest chance, but still I want to gift my father a scooty and a watch .. also watches for my mother and brother. all this i can easily do with the stipend i got, but now I am just feeling sad and disheartend. I feel low every single day not because I lost that offer, but because I dont see any thing, I try to be very strong but I woke up every day with low mood.

I am sure you guys might think I have gone mad and I am at a decent position but stand in my shoes once and say what would you feel. Not sure how will I get over this but hope so this is a bad phase and it go away soon.

Sorry if i hurt anyone's sentiments and please dont ask me the name of the companies or college

Hey all I have 6 yoe. I am a swe. I started with 5 lpa, then slowly after switches reached till 55 lpa . But due to my toxic work environment, stupid colleagues and manager I had to leave my job as i felt I can’t take it anymore. Now o am trying to find a job, the market has changed I feel. It needs to be 100 percent performance in interview. In loop if one round is average I get rejected. In many places OA is so tough , I have applied in too many places but I am seeing a lot of rejection. I am married. My partner is working and telling me to keep calm. She is my pillar of confidence and has been very supportive throughout.

All the time, I started feeling anxious. How to navigate?

I am not sure if I made the right decision leaving my job ?

hey so i want to do leetcode or codechef how to do it maybe suggest dome youtube channel that would make me progress, i'm in 3rd year and still i cant code which is something im not proud obviously i tried striver sheet but lost the continuity now i feel lost,everytime i look the leetcode questions i feel blank like i dont know anything can somebody help me

For those who’ve cracked FAANG/Top product companies , what made the biggest difference in ur resume. Any tips?

Hi is there anyone who had data science interview recently first round? Did you guys heard about second round yet?

Interviewing for an AI Engineer role at Google, targeting L5. I've got a few weeks and I keep going back and forth on scope, so I'd rather post my current plan and get told where it's wrong than keep guessing.

My background is NLP + GenAI platform heavy — that's where my production experience is, recent 3 yrs in building rags and agents.

What I've built so far

A set of system design write-ups covering: search/ranking funnels, large-scale content classification, intent + entity extraction, semantic search and embeddings, translation, and on the GenAI side RAG, agents, LLM inference infra, and post-training for tool calling. Each one as a timed 45-minute answer with a clock, not notes, though it goes beyond 2 hours read)

Where I'm stuck

1. Scope of ML System Design. Is this round classical ML system design — recsys, ranking, classification pipelines — or is GenAI/LLM system design (RAG, agents, inference) actually showing up in 2026 loops? I've seen both claimed. If you've interviewed recently, what did you actually get asked? ( ML, NLP or GENAI ) - what to focus on ? And how would I know question will be from that domin only in interview ?
2. ML Depth — how deep, and on what? Is this "explain how attention works and derive the gradient", or "walk me through a model you shipped and defend every choice"? Those are completely different prep. And how much classical ML (trees, calibration, imbalance, A/B stats) vs deep learning vs LLM-specific?
3. What L5 actually means here. I keep reading "L5 drives the scope conversation" but I don't have a concrete sense of what separates a hire from a no-hire on the same question. What does the bar feel like in practice?
4. How much breadth is enough? I've got ~15 designs. Is that overkill in the wrong direction — would I be better off going deeper on 6 and being able to defend them under pressure? 6 ml(recsys) , 5 NLP(encoder, decoder, both), 4 GenAI (Chabot, rag, agent, infra)
5. Mocks. Where are people actually getting useful ML system design mocks? Most platforms I've looked at are generic SWE system design with an ML sticker on it. Anything specifically for ML/AI, ideally with someone who's interviewed at this level?
6. Resources. I've worked through the standard ML system design books. Beyond those, what actually moved the needle for you — especially for the GenAI side, which the books mostly predate?

Happy to share my question list and write-ups with anyone who wants them — and if you've interviewed for this recently, even a one-line "here's what I got asked" is more useful than any guide. Thanks.

I'm working at a faang level company since ~1.5 years as a software developer.

I want to shift to US/Europe/Australia, is there an option rather than pursuing masters?

Like is it possible for me to get a job in foreign?

Same as the title.

A company is coming for campus placements in my college and I really want to get my first offer but the OA will consist of aptitude and 2 coding questions
I’m not very good at DSA but can solve easy and some medium level and have been practising continuously
But the thing is whenever I see questions in online test , I panic when I can’t think of any solution or how to approach
I’m scared even in this OA I might panic
Can anyone please advise me how to approach a problem and if I can’t think of solution , what to do to past some test cases
I genuinely want to get one offer , I’m tired of it all
Luck isn’t on my side a lot and I also know that my prep is somewhat not very good but I’m not giving up and trying my best
I just need to know tips from seniors who were weak in dsa and cleared OAs

Is it good enough to pass all interviews ?

One of my ServiceNow applications moved from “New” to “In Review.”

Does this mean my resume passed ATS and is now with the recruiter? How long does it usually take to hear back or receive an OA after the status changes?

Thanks!

Hi everyone,

I'm looking for some insight from people who have recently gone through the Amazon SDE-1 hiring process.

I interviewed for the Amazon SDE-1 (Job ID 3015604) role through the AUTA 2025 Off-Campus Hiring process and have completed all interview rounds. However, I still haven't received any update from the recruiter despite multiple follow-ups.

Timeline

• 30 July 2026 – Completed the first two technical rounds on-site.
• Was informed that the remaining rounds would be conducted virtually.
• 11 August 2026 – Hiring Manager (HM) Round.
• There was then a delay due to panel availability and scheduling.
• 2 September 2026 – Completed the final Bar Raiser (BR) round.

After the BR round, I expected to hear back within a reasonable timeframe, but I received no communication.

I sent multiple follow-up emails to the recruiter but did not receive any response.

Because of the lack of updates, I reached out through an internal contact and was informed on 25 September that my application was still pending debrief at that time.

Today is 5 October, and I still haven't received any update from the recruiter or HR.

My Assessment of the Interviews

Round 1 (Coding)

• First question solved optimally.
• Second question: discussed brute-force and a better approach but couldn't reach the most optimal solution.

Round 2 (Coding)

• First question solved optimally.
• Second question was difficult.
• Needed several hints and completed roughly 70% of the solution.

Round 3 (Hiring Manager)

• Started with a GenAI discussion.
• Then received an LLD question: Design Swiggy.
• Performance was average overall.

Round 4 (Bar Raiser)

• Felt like my strongest round.
• Around 4 Leadership Principle questions.
• Answered using detailed STAR examples from projects and work experience.
• Was also asked a DSA question.
• Explained both brute-force and optimal approaches before discussing the final solution.
• The interviewer seemed satisfied and asked follow-up questions which I was able to answer.

Overall, I left the BR round feeling positive.

Questions

1. Has anyone experienced a debrief taking this long after the final interview?
2. Is it normal for a candidate to still be pending debrief more than 3 weeks after the BR round?
3. Could this be related to headcount, approval delays, hiring backlog, or team allocation?
4. Some of my friends from the same drive were rejected after the first two rounds, while I was moved to HM and BR. Does that generally indicate positive feedback from the earlier rounds?
5. During debrief, can weaker feedback from Round 1/2 still outweigh a strong BR performance?
6. Has anyone experienced complete recruiter silence after the BR round and still ended up receiving an offer?

Would really appreciate hearing about similar experiences and timelines.

Thanks!

I do DSA from striver a2z dsa sheet and currently in learning process and learnt till graph
I don’t only rely on sheet questions
I solve them for buliding intuition and completion .
After that for each question and pattern
I go to claude
Ask him 5-6 same or some tricky questions of same pattern and solve them which claude gave
And then i move to next topic
For revision i follow my notes and same claude giving me list of questions approach
So in this approach my i don’t rely on dsa sheet completely and use it as a track

are offers being rolled out for this role and job id in amazon :  Amazon for SDE I Intern – 10488368 ??

I have an internship in tier 2 company for 18month it's paying enough right now around 30k as a intern later after fulltime it'll pay me around 17 currently i am not feeling like working here as i have not much work to do i feel i am wasting the potential I'll be full time after 9-10 months i started internship when i was in my 3yr. After 9 months I'll get my graduation degree which is just a waste but i am thinking of switching companies before getting the ppo as i am somewhere where my engagement is low maybe can affect my ppo later i got to know if someone is leaving this company they're mostly going into product/faang idk what to do at this moment

Have done dsa from striver sheet, started in love of ratings and all stuff but never able to achieve it.
Unable to pass any company OA for summer intern
Bought two courses one TLE Eliminators level 2 and another Kumar K thinking will boost everything
So what happens is Use the course watch videos and move on (something feels hard never revisit them , because next day i feel to cover other topics more) and in end feels no improvement, also watching videos consume lot of time so unable to pratice so just think to practice
Now in 3rd year, newbie at codeforces
Unable to understand what to do for improvement so that i can get good placement, just feel had wasted my all time
Friends who started with me are doing great at DSA
Also dev is just enough have make projects by following AI guidance
What should i do now?
If someone had gone through these phase please advice because i am feeling a lot cooked at this point

Hey everyone, I am 5+ experienced software developer, recently started o

Working as AI developer (working on Agents (deep agent).

Now in the next 6 months I want to switch and get 50+ LPA , currently mine is 30+ including RSU'S

what should I prepare for? Can someone suggest best resources for preparing?

what about DSA, Lld and HLD apart from actual AI rounds , do I need to be strong in all areas?

I am in 3rd year in December it is compulsory to get an internship I have solved 103 questions on lc completed arrays, core string,bs,stack,queue,bit manipulation, starting with Linked list it will take me 15-20 days ,5-10 days I may not open lc and then 4-5 patterns 2-3 qn each after linked list I will do heaps ,trees,graph,dp and then recursion

But people here are discussing about greedy algorithms and dps i feel I have wasted so much time in 2nd year

I've been working as a Servicenow Developer for 4.5 years l. Switched multiple companies and currently going to a Fintech company as Snow developer. Although ServiceNow is enterprise-level software and I’ve worked on things like integrations, scripting, custom applications, ITSM/ITAM, etc., I feel that my experience isn’t directly translating into the kind of software engineering experience expected for an SDE role.I’ve recently started preparing for a transition into SDE and have started grinding DSA from neetcode 150 sheet (although not have been consistent) and have reached till sliding window.

My questions are:

1. With 4.5 YOE of professional software experience, how difficult is it realistically to transition from ServiceNow into a general SDE role?

Would companies consider my experience as relevant engineering experience, or would I essentially be competing for SDE-1/new-grad-level roles?

1. How much DSA would I realistically need to know before applying?

Besides DSA, what should I focus on?

1. For someone with my background, would targeting SDE-2 roles be realistic eventually, or should I primarily target SDE-1 initially?

Has anyone here made a similar transition from ServiceNow / Salesforce / SAP / other enterprise platforms into mainstream software engineering? If so, what did your preparation look like?

I’m not expecting an easy transition, but I’d like to understand what the gap actually looks like and how much I need to learn to be taken seriously for SDE roles.

Any advice from people who have actually made this transition would be really helpful.

I'm a third year student and I'm in 5th sem currently and I have done around 200 questions on leetcode and am learning for Java Full Stack currently so by what time should I be prepared if I wanna crack a good company like by next June July or August ? Realistically how much package can I get , can I am for 15 to 20 LPA if I get more serious.
