Amazon Software Engineer interview questions

I got contacted by a recruiter a few days after applying online. I had one phone interview that went pretty well and got contacted for an on-site interview at their head quarter in Seattle. I had 4-5 interviews back to back with no break and met one person during each interview. That was interesting to meet people from different areas who asked me questions that were quite various. I had one of the best interviewer I have ever met during one of those interviews. A couple of days after those interviews, I got an email telling me that they will start working on an offer.
