Amazon Software Developer interview questions

The interview was for 45 minutes and was a screening interview

Had 2 phone interviews, one of them had questions on algorithms and the other on Datastructures and coding. Was called for 1:1 interviews at their Seattle dev center. The first one was about designing concepts and classes, and also UI for the Kindle. Free form discussion mostly. Second interview was with the prospective manager. Somehow this was what went wrong. We just did not understand each other and the questions were on things like "How would you work with someone who is not doing any work and has no interest in doing the work assigned to him" etc. One technical question after that which I found answerable but got confused midway even though I had the idea right. Last 3 interviews were all technical and the experience was very positive. They did not make me an offer. I believe the one with the manager was the make or break one and I screwed it up bad.
