Amazon Software Development Engineer interview questions

The process took about 2-3 weeks. First-round was a codility test with 3 tasks every of different complexity levels (easy, medium and). After successfully passing the first stage, I was invited to onsite interview. The interview was about 4 hours with the classical Amazon approach. The overall experience was good except that they don't provide feedback.

Initial phone call with the recruiter. Then online coding test, two algorithm questions and about 45 mins long. After I went to onsite interviews with four people. Everything well organized. Nothing to complain. Response time wasn’t too long. They returned in a week after the interview.
