How it went
A few things to keep in mind: -->Don’t jump straight to the optimal solution. Start with a simple/brute-force approach, dry-run it on a small example, and explain why you thought of that first. -->Be explicit about time and space complexities at every stage (brute → improved → optimal). It’s very, very important. -->Communicate clearly: restate the problem, confirm constraints(very important), call out edge cases, and narrate your reasoning. Validate with edge cases (empty/single element, duplicates, negatives/large values, off-by-one, etc.)

How to prepare
I got this opportunity through Amazon Hackon Season-5, where our team got selected into top-130 teams out of 50,000+ teams. Regarding preparation, I redeemed Leetcode premium through LC coins, and practiced recently asked questions at amazon before the interview, it really helped me a lot, apart from that i was already grinding DSA from the past 1 year giving so many contests, so it was not that much hard for me.
Their background
I'm a final year undergrad from Tier-1 NIT, have solved nearly 1500 problems on leetcode over the past 1 year.
Round by round
- 1
Online Assessment (OA)120 min
OA Details: Duration ~2 hours. Part 1: 2 DSA questions on HackerRank (no camera). I solved 1 completely and ~80% of the second. Part 2: WorkStyle Assessment (this was honestly frustrating, but the key was to remain calm and answer intelligently).

Technical Round60 min
The interviewer joined on time, introduced himself, and asked me to introduce myself. Without asking about my resume, projects, or Leadership principles(LP's), he directly shared a live coding link. He asked me two LeetCode medium problems:
-
Asteroid Collision
-
Minimize the Maximum Difference of Pairs For each question:
-
I first explained the brute force approach.
-
Then coded it, and wrote time and space complexities below the code.
-
Next, he asked me to optimize the solution. I discussed the optimized approach, dry-ran it on a test case, handled his counter-questions, and then coded the optimized version too.
-
Again, I mentioned TC/SC and dry-ran a test case. He looked satisfied with my explanations. Pro Tip: Write clean, modular, and readable code. Use helper functions wherever possible. It helps you a lot during dry runs and leaves a great impression on the interviewer.
-
Surprisingly, the interview had no technical discussion beyond DSA, no project questions, no internship discussion, and no LP questions. At the end, he only asked if I had any questions. I asked him two, and the interview wrapped up in 55 minutes.
