Amazon Non Software Development Engineer interview questions

Typical algorithm/problem solving stuff. They all were happy during the interviews but the decision was to not put an offer.

The recruiter contacted me and organized a few phone screens with skilled engineers. There was about 10 days between interviews. They asked intensely difficult technical questions, but were friendly and supportive. Brush up on network protocols and hash tables! The next stage was 5 on-site 1:1 interviews of about an hour each. Very difficult! No offer yet...
