I applied through college or university. The process took 1 day. I interviewed at Amazon in Jan 2010
Interview
Two 45 minute in person interviews with engineers. Overall very relaxed atmosphere. Interviewers were dressed casually. Mostly open ended technical questions. Only 1 question where interviewer was looking for a specific answer. Cared more about general problem solving ability and thought process. Got a decision in < 24 hours after interviews.
