Amazon SDE intern interview questions

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.

I had an on campus opportunity for 6 month internship in Amazon. We first had an online test which has DSA questions followed by a behavioral round which was likely assessed based on their Leadership Principles.
