The first interview was a phone interview with a single member of the team I would be working with. She was a very pleasant and told me a small bit about the job that I was interviewing for, then rapidly moved on to the "quiz" portion of the interview. I had purchased the Progamming Interviews Exposed book and studied up for about a week, it's pretty representative of the kind of questions you'll be asked. Basically, computer science puzzles about algorithms. Just google "amazon interview questions" and you'll find most of the questions you'll be asked. The first interview lasted about 45 minutes. I fumbled a bit, but felt I had a good rapport with the interviewer. A few days later I got another call to schedule a second phone interview. This one was with the actual team leader and was a quite a bit more stressful. The questions were also less well defined. He asked about programming techniques that I'd use to scale a certain type of web application. I sort of muddled through that with a lot of thinking out loud. He then moved on to asking me to design the control software for an elevator control system. Again, I felt like I sort of fumbled my way through. I ended up not getting the job, though also not terribly surprised.
