Amazon Software Engineer interview questions

Applied online and was contacted three months later by email with a link to a timed programming assessment. There were three problems to complete in 90 minutes. After completing the assessment, I was contacted again by email with an invitation to an onsite interview in Seattle. The onsite interview was completely technical with 4 interviewers, 40 minutes each.

interview by phone. As a internship recruiting process, there are two people talking with you. First one asks you something about project design, second one gives you some programming problems to solve.
