Amazon SDE-intern interview questions

Round 1: online coding in HackerRank (from easy to medium) Round 2: technical HR round. You need to code in front of the interviewer(mostly DSA problems focus on dynamic programming and tries)

In my Amazon SDE intern interview, the process began with an OA (Online Assessment) that included debugging, data structures, and logical reasoning. After clearing it, I had a 45-minute virtual technical interview. The interviewer was friendly and started with a quick introduction, followed by one DSA question. I was asked a BFS-based problem similar to Rotten Oranges (multi-source BFS). I explained my approach, edge cases, and optimized the code. Then we discussed time and space complexity. Finally, I was asked a recent problem: Find the number of unique paths in a grid with obstacles. The interview concluded with a few behavioral questions.
