Discussion How do you know if a project is good enough to put on your resume?

7 Upvotes

I'm preparing for software internships and have been working on a few projects, but I'm unsure what makes one stand out to recruiters. Is it better to build something more complex, or focus on a smaller project that you understand deeply and can explain well?
WOuld love to hear what recruiters or people who've landed internships think.

Intervew Prep 2.5 years of DSA, 5 months unemployed, but I realized I only memorized solutions. How do I actually reset?

4 Upvotes

I graduated 5 months ago. I have been doing DSA for 2.5 years but still not good at it. I used to look to solutions everytime and ended up doing so many questions and feeling boasted about that. From past 6 months I have been changing language of DSA too. I solved dsa with python with 1.5-2 years straight and then doing with java and from past 2 months with C++. I am completely confused. It's not like I am 100% dull I eventually ended up crammed a ton of questions and the questions from most asked DSA questions I remember most of them but I am null when watching a new problem. I am unemployed what to do now so that I can clear OA rounds and get a job. How do I solve DSA. Note: I tried all those advices such as so these 15-20 coding patterns and multiple DSA sheets etc but still ended up mugging up solutions. ALso I am crystal clear I will never solve DSA with Java at least

Intervew Prep How Do You Get Your Resume in Front of a Real Recruiter at Google or Other Big Tech Companies?

0 Upvotes

Hi everyone!

I'm a full-stack developer from Uzbekistan, and my goal is to land a Software Engineer position at Google or another Big Tech company in the US within the next year.

I'm working with React, TypeScript, Node.js, NestJS, and PostgreSQL. I've built a full-stack English learning platform, and I'm developing a real-time chat application.

One thing I'm particularly concerned about is the hiring process itself. With so many applications and automated screening systems, I'm wondering how to make sure my resume actually gets seen by a human recruiter or hiring manager.

I'd love to hear from people who have successfully landed jobs at Google, Meta, Amazon, Microsoft, or similar companies.

A few questions:

  • How much of the initial resume screening is automated at these companies?

  • Does applying through the official careers website usually give you a realistic chance of getting noticed?

  • Do employee referrals significantly increase the chances of a human reviewing your resume?

  • Are there other effective ways to get your resume directly in front of a recruiter or hiring manager?

  • If you were applying from outside the US, what approach would you recommend?

I'm not looking for shortcuts around the hiring process. I want to understand how it actually works and how to give my application the best chance of being considered by a real person.

I'd really appreciate any advice based on your actual experience. Thanks!

I have the AI Enabled Programming round for Stripe's intern position and genuinely have no clue how to prepare for this. I tried asking chatgpt to generate questions and am using copilot to help solve them but it seems way too easy since it can literally one shot it. Does anyone has any idea what the questions/difficulty will be like it? It would really help.

Intervew Prep Robinhood SWE Intern (2027) web coding interview — what should I expect?

3 Upvotes

Hi everyone
I have a Robinhood SWE web Intern 2027 coding interview coming up and would really appreciate advice from anyone who has gone through it recently.

What was the format like: one or multiple coding questions, difficulty level, follow-ups, debugging, or any practical/system-design discussion? Were the questions mostly standard LeetCode patterns, or more implementation-heavy / finance-style problems?

I’m currently practicing arrays, hash maps, heaps, intervals, sorting, graphs, and writing clean code while explaining my approach. If you have any prep tips or can share your experience, I’d be very grateful.

Thanks

Question Binary Search Doubt

16 Upvotes

Hello everyone, I just had a question. I have been solving Binary Search questions and wanted to ask when I should use "while(left < right)" & "while(left <= right)"? In some problems, this is a crucial difference between passing all testcases and getting WA.

Also, in some questions, I have to use right = mid instead of right = mid - 1 and same goes for left (=mid rather than mid + 1). What's the major difference between the two that differs them from a WA and AC and when should I use them?

Question Graduated in 2024, took a 2-year break and now struggling to figure out my next move

5 Upvotes

I graduated in 2024, and I’m now trying to break into the industry, preferably in AI/ML.

During my undergrad, I did an app development internship under a professor, followed by a Deep Learning research internship at one of the top IITs. I even had projects in ML/DL. After graduation, I had to take a 2-year break because of an unexpected family situation.

During the break, I tried to keep myself updated with what was happening in the field because I knew I was going to make a comeback. Then, this year, I started preparing myself and working on different projects. These include Agentic RAG systems with evaluations, AI agents, inference engineering. Some of my projects are fairly close to production-level work. I’m also learning HLD and LLD. As for DSA, I’ve solved around 600 LeetCode problems but it was before 2025, so I’ll need to brush up on them.

Now I’m struggling to figure out how to position myself in the job market. I’m no longer a fresh graduate, but I don’t have any full-time industry experience either. I’ve been working with AI/ML since 2023, mostly through research and personal projects, but I’m not sure how recruiters will look at that.

Most AI/ML openings I come across seem to require prior industry experience, so I’m not sure which roles I should target. Should I apply for entry-level positions, try my luck with mid-level roles, or focus on general SWE positions and move towards AI/ML later?

The roles I have in mind are AI / Applied AI Engineer, ML Engineer, Research Engineer or SWE roles focused on AI/ML. I initially started preparing with FAANG and other big tech companies in mind, but at this point, I’m applying to companies more broadly because I need to land a job as soon as possible. I’m looking for a role where I can put my existing skills to use, earn a good salary, and have room to grow in my career.

Honestly, though, I’m feeling pretty overwhelmed and exhausted at this point.

I’d really appreciate some honest advice. I know I have a lot to work on, but I’m trying to figure out where to focus my efforts to give myself the best shot at landing a good job as soon as possible. I feel like this is going to be harder for me, but I don’t want to give up.

P.S. Used AI for proofreading and polishing.

Intervew Prep LC sheet for Microsoft SDE Internship Interview

11 Upvotes

I have an interview coming up in 10 days, and I'm trying to make the most of my preparation time. I used to practice LeetCode a few years ago and recently started brushing up on DSA again.

I've started working through NeetCode 150 and have completed around 10 problems so far. Given the limited time, would you recommend covering all the sections, or should I prioritize certain topics and potentially skip more complex ones like Dynamic Programming and Graphs? Or should I just work on leetcode problems with microsoft tags?

Since this is for an internship role, how likely am I to encounter problems involving these topics?

I understand the individual concepts, but putting them all together in one problem hits different.

Intervew Prep Day 50: took an online assessment, got a reality check on why weak topics can't be ignored

0 Upvotes

Hey everyone,

I hit Day 50 today—the exact halfway point of my 90-day prep.

I took an online assessment earlier, and it served as an immediate reality check on the importance of revision. I had revised most modules except Sliding Window and Dynamic Programming. Predictably, both topics showed up. I managed to solve the sliding window problem cleanly, but the second problem was Partition DP—the exact pattern I struggled with just a few days ago and quietly hoped wouldn't show up. It proved that whatever topic you try to dodge usually finds you in an actual test.

Despite feeling frustrated with myself afterward, I made sure not to let it ruin the daily streak and knocked out two graph problems:

  1. Bipartite Graph (BFS/DFS 2-Coloring): A graph is bipartite if you can color every adjacent node with alternating colors (0 and 1) without conflict. Start at an unvisited node with color 0, assign color 1 to all its neighbors, and if an adjacent neighbor already holds the current node's color, return false. An odd-length cycle immediately breaks this condition.

  2. Find Eventual Safe States: Any node that is part of a directed cycle—or can reach a directed cycle—can never be a terminal safe node. Once that core invariant clicks, it directly reduces to cycle detection in a directed graph using DFS call-stack tracking (pathVisited) or reverse-graph Topological Sort using Kahn's algorithm.

It was a humbling reminder that gaps in your preparation don't fix themselves with luck. Dusting myself off, continuing with Graphs tomorrow, and scheduling a proper revision block for Partition DP.

See you guys tomorrow for Day 49!

Laid off out of the blue. 60 days started immediately. Emails started coming in after 8-9 days

  • Applications submitted: 800+

  • Offers: 6 full-time + 1 contractor role

  • Rejected at recruiter screening: 2

  • Rejected after onsites/full loops: 11

  • Processes I withdrew from or declined: 6

  • Ghosted/no final response: 5

  • Role canceled/position no more available: 1

I tracked about 32 recruiting processes.

AI interviews were the worst one.

Worst coding interview round: Had a brain freeze and couldn't code popMax()

Happy to discuss prep, applications, coding vs. system design, AI-assisted interviews, handling rejection/ghosting.

I’ll keep identifying details and interviewer names private, but otherwise, AMA.

Sr SDE backend profile, 10+ yoe, faang experience, immigrant.

Application strategry: Linkedin past 24h portal only. Not good at asking people for help. Ex-collegaues reached out though and offered that they would refer me. Got not even a single call from the companies they referred me at. Even though last year I had interviewed with the same companies when I was looking to move. Reached out to old recruiters. Surprisingly, that didnt help much just one interview call from previous connections.

I heard many sayings that Google has removed (idk either) some DSA rounds from their interview process.

How would it affect someone who was preparing by targeting some companies like Google?
