Gave the amazon interview on May 10, 2021. There were 4 rounds; 3 coding and one system design. The coding questions were leetcode easy/medium. The system design question was not something which I practiced, but it wasn't very tough. I was able to solve 2 out of 3 coding questions, for the 3rd question I was halfway through but time was up. May be that was the reason for my rejection.
