Amazon Software Development Engineer interview questions

Was asked data structures and algorithm. All interview rounds were completed on the same day. Overall was an average experience, the results got delayed till about a month from interview.

Very friendly and supportive technical interview. Spoke with recruiter on first call and SDE for second phone screen, which was technical in nature. Asked an easy question to begin and then built upon that. Could see that there were about 3 layers to the question depending on skill level.
