SDE-2
Interview Rounds
Low-level design problem with 2-hour submission window before discussion. Evaluated solution approach and tradeoffs between different scenarios.
Candy Distribution (Greedy), Course Schedule with prerequisites. Puzzle: Implement rand12() using rand6() with equal probability.
Standard behavioral questions plus technical background. Career motivation, recent project details, database selection rationale (SQL vs NoSQL).
Tips & Advice
Applied via referral. DSA round was okayish - struggled with equal probability requirement. Got rejected primarily due to low confidence in HM round combined with adequate but not strong DSA performance.
SDE 2
Interview Rounds
2 hard DSA problems. One on DP, one on graphs. Needed optimal solutions to clear.
DSA - Solved one problem fully, got stuck on the second (interval scheduling).
Low-level design - Design a rate limiter. Good discussion but made some mistakes in the implementation.
Tips & Advice
Bar is high - similar to Flipkart. DSA needs to be strong. They expect production-quality code in LLD rounds. Got rejected after round 2. Feedback was that LLD implementation had bugs.
