Amazon Software Development Engineer interview questions

I got 3 rounds for at least 3 hours. Each round contains one BQ and one coding question. They ask what is the project I was proud of. What would you do if you have limited time for 3 due at the same time, etc. Coding questions covered HashMap, HashSet and dynamic programming.

It's a lengthy process that takes up an entire morning or afternoon, depending on the time you are scheduled. You will have 4 technical interviews and one with someone from HR. The technical interviews will try to see different skills, problem resolution, architecture and design, etc. And each of them will also try to test you for one of Amazon's "leadership principles" (they do send you info on that when you get contacted and scheduled for the interview) so try to read them and come up with an example of a situation in which you have shown each of them, you WILL get asked for one of them by each of the technical interviewers.
