Amazon MBA Programmer interview questions

Received an email asking for dates and times I was available for a phone interview. We agreed a date and time. They were very professional and answered all my queries promptly. First telephone interview lasted 35 minutes. Interviewer was very friendly and and put me at ease. Had 2 competency based questions and then asked me if I had any questions. It was a positive experience overall. Unfortunately I wasn't successfull but they sent a reply a few days later explaining the reason. I had a very good impression of the people I had contact with.
