Amazon Software Engineer interview questions

One hour interview. Was asked to describe my previous projects, what were the challenges, how do i approach them, what do I consider as my best achievement so far. He described the usual problems they solve in their department. Overall very pleasant and polite person. Apologized for asking to write code and read him over the phone, but it was not a problem to me.

Interview consisted of one phone screen with H/R, two phone interviews with engineers, then followed by a programming assignment. After passing all these hurdles was brought up to the corporate Head quarters for an on site interview. On Site consisted of 4 interviews (three techinical, one soft) which included programing problems and general technical discussions.
