Amazon Software Engineer interview questions

This was a recruiting drive. I was contacted by email and asked if I wanted to participate in a recruiting drive in Boston. I had 4 hour long interviews one right after the other at a hotel. Amazon had rented out a suit of conference rooms for the event. The interviewers were pleasant, and seem to have a set of questions (or types of question) that they asked. Each interviewer seem to focus on different things. The interview process was very STAR (situation, task, action, result) oriented. Look this up in the web, it's worth it. After the question, you were given a problem to work on. The problems are not difficult, just take your time and talk it out. Talking through the problem is really important since it can save you from going down the wrong path.
