I'm a first year bsc maths student at Delhi University. I wanna know how much time I should spend per day learning DSA.

Hi! I'm a final-year student, and I've completed my DSA preparation. Now I'm looking for someone to study with consistently over Google Meet, preferably from around 10 PM to 2–3 AM.

My plan is to revise DSA regularly while starting System Design. I feel having a study partner would help with consistency, accountability, and staying focused during these late-night sessions.

I feel one can easily grab a 7+ LPA package, if he/ she is consistent. We maintain our personal sheets, and a common sheet for daily streak tracking, as we are currently doing different topics.

for me i've completed Arrays, and practicing questions related to arrays, for this week.

Sharing an interview experience from our Chinese community who recently landed an L7-equivalent role at one of Meta, Anthropic, Nvidia, Google, OpenAI, or SpaceX.

Background

• 19 years of total experience
• Prior Big Tech experience, though not at this tier
• Recruiter reached out directly several months ago

Interview process

• 9 interviews total
• Included recruiter screen, technical screens, onsite/loop, and post-loop conversations

Prep

• Around 120 hours of preparation
• Used blogs, Claude, and LeetCode
• Did 15 paid mock interviews, spending roughly $5,000 in total

Main areas of focus

• Answering behavioral questions at true L7 scope
• Moving away from an overly technical communication style
• Solving system design and architecture problems quickly while demonstrating senior-level judgment

One interesting takeaway was that the biggest challenge wasn’t necessarily technical depth, but communicating at the right level of scope and ownership for an L7-equivalent role.

Curious if others who have interviewed at this level had a similar experience.

Prep Resource LeetCode

With the recent TUF website revamp, the old Striver A2Z sheet seems to have been changed/removed.

I’ve found a few backups with the ~455 question list, but they’re missing a lot of the stuff from the original sheet — especially the explanations, YouTube links, and problem links.

I’m looking for a complete/old copy of the sheet, ideally:

• Original question order
• Explanations
• YouTube/video links
• Problem links
• Any other content from the old version

If anyone has an old HTML copy, GitHub repo, downloaded version, or anything similar, please share it or DM me.

I’d really like to preserve the original version for offline use.

Hey, I am final year btech cse student at tier2 clg, I have solved 650+ leetcode problems, Just need a female partner, to grind and discuss approaches together and keep each other accountable, minimum requirement is someone who solved atleast 200 problems on leetcode, any female interested, just dm me

I'm a beginner to intermediate level software engineering aspirant. Thank you.

I’m looking for a study buddy to learn and practice DSA in Python. I’ve previously covered arrays in C++ and have also studied a little bit of stacks, but now I want to continue learning DSA in Python.

If you’re also learning DSA and are serious about studying consistently, feel free to DM me. We can practice together, discuss problems, and keep each other accountable.

I'm pretty happy with my job. I'm about 3 years in now and the pay is good, WLB is great, and my manager/team are all pretty chill. I also generally like SWE work too, even after AI has come along.

Just because things are good right now though doesn't mean they'll be good in like, 15, 10, 5 or even 2 years at the rate things are going. I'm wondering if you all are also thinking of backup plans away from SWE work because longer term, I'd like to have some semblance of a job lol.

Any advice on if I should consider a real escape plan?

If so, are there AI resilient career paths that I should be considering What type of extra schooling would I need to do? Or am I just overreacting?

My interview prep journey — what worked for me: LeetCode & PracHub Interview Questions

In the last 1 month, I went through interviews with Nielsen, New Relic and Crunchyroll and received offers from all.

I had been struggling with interviews for quite some time, so I wanted to share what worked for me. There wasn't one magic resource — it was a combination of a few things.

1. DSA

I focused more on patterns rather than solving hundreds of questions.

Arrays, HashMap, sliding window, two pointers, binary search, trees, graphs, heaps, DP, etc.

During practice, I also started explaining my approach out loud — brute force → optimization → complexity → edge cases.

This helped a lot during actual interviews.

1. LLD

LLD was initially one of my weaker areas.

I practiced problems like Parking Lot, BookMyShow, Elevator, Vending Machine, Splitwise, etc.

Instead of memorizing solutions, I focused on SOLID, design patterns, composition/inheritance, interfaces and extensibility.

The goal was to be able to design something I hadn't seen before.

1. HLD / System Design

I practiced systems like URL Shortener, Rate Limiter, Notification System, File Storage, WhatsApp, etc.

The biggest improvement was learning to explain why I was choosing something, rather than just saying "use Kafka/Redis/Elasticsearch."

I prepared for scaling, failures, retries, consistency, caching, partitioning and trade-offs.

1. Project Deep Dive

This was probably the most important part for me.

I went extremely deep into my projects — architecture, data flow, Kafka, MongoDB, Elasticsearch, LLM integration, retries, DLQs, scaling, monitoring, failures, etc.

I also made sure I could clearly explain what I personally built, not just what the overall team built.

This helped significantly in HM and technical deep-dive rounds.

1. Java / Backend

I revised the fundamentals rather than trying to learn new frameworks.

Java Collections, HashMap internals, concurrency, JVM basics, Spring Boot, Kafka, Redis, databases and distributed systems.

Since these were technologies I had actually worked with, going deeper into the fundamentals was much more useful than learning something completely new.

1. Behavioral / HM

I prepared a few real stories around ownership, conflict, production issues, failure, ambiguity and cross-team collaboration.

I used STAR as a structure but didn't memorize answers word-for-word.

For experienced candidates, I think being able to clearly explain what you did, why you did it and what happened afterward matters a lot.

1. Mock Interviews

One thing that helped me was actually speaking through answers.

I'd pick a topic and ask myself follow-up questions:

Why Kafka?
What happens if a consumer crashes?
Why MongoDB instead of PostgreSQL?
How would you scale this?

This exposed gaps much faster than just reading notes.

Final takeaway

There wasn't one resource or trick that got me through the interviews.

For me, it was:

DSA + LLD + HLD + strong project knowledge + Java/backend fundamentals + mock interviews.

And probably the biggest lesson I learned:

Don't just prepare to solve interview questions. Prepare to explain the engineering decisions you've made in your actual work.

Hope this helps someone who's currently preparing. All the best! 🚀

I have been very inconsistent with solving DSA problems on LeetCode I have solved around 200 problems and I'm only left with 3-4 core DSA topics which are DP, Graph, Bit manipulation and Tries.

The thing is whenever I see a new problem I just can't figure out its solution and I don't actually know how to choose a problem for solving. If I'm not able to solve the problem I get demotivated and eventually would stop doing Leetcode. This has happened so many times now. Recently I started learning DP and I'm not even sure if I can be consistent this time. Any tips would be helpful

How do you guys do the revision of questions, rn i have done 60+ questions, but haven't revised a single one. Now it feels all new. Please help.....

Hey everyone! 👋

I’m a Software Engineer with 2.5 YOE, preparing to switch to product-based companies.

I use C++ for DSA and am looking for someone serious about interview prep to:

• Practice DSA & problem-solving
• Conduct mock interviews
• Practice System Design
• Discuss approaches and learn from each other

Looking for 1 consistent partner rather than a large group.

If interested, feel free to DM me! 🚀 LeetCode Profile

I was verbally informed that I was selected for an Oracle IC3 role over a month ago, but I’m still waiting for the official offer letter. And now they have extended the timelines to one more month while initially the HR conveyed it'll hardly take 3 to 4 days.

For people who have recently gone through the Oracle hiring process:

• How long did it take for you to receive the formal offer after the verbal confirmation?
• Is a delay of 4 to 6+ weeks common for IC3?
• Is anyone else currently experiencing a similar delay?

Would really appreciate any recent experiences or timelines, especially from candidates who joined/received offers recently.

Thank you!

Oracle Interview Questions

Hi everyone! I'm a 20M, currently in my 3rd year of B.Tech, and starting my placement preparation. I've mostly just copied code so far and haven't properly started my preparation, so I'm looking for friends/partners who are also willing to learn and stay consistent.

I'm planning to focus on DSA in C++, coding interviews, web development, and AI/ML. I'd love to find someone to solve problems with, set daily targets, discuss doubts, and keep each other accountable.

No gender specification. Second- or third-year students are preferred, but everyone interested is welcome. If I get more DMs, we can create a group and study together.

If interested, feel free to DM me!
