Amazon Software Development Engineer (SDE) interview questions

Straight forward, onsite 3 total rounds, 2 leetcode medium, 1 oop coding problem. Behavorial questions at the end of each round on amazon principles. Super chill, pretty hard but not impossible

After 5 months of application received interview invite and had a loop interview. First round was coding completely. Leetcode based. Second round is behavioral. Third round mix of coding and behavioral. first and second rounds went very well the interviewers were very impressed but messed up in third round in the coding part.
