Amazon Software Development Engineer interview questions

Applied through college career center. Got an email from a recruiter asking to schedule an on campus interview about a week later. Two 45 minute technical interviews on campus. The questions were similar to the ones you would find in CTCI. Personally didn't think it went very well, but got the offer a couple days later.

They invited me for a day of on-site interviews. I met 4 engineers and 2 managers. In addition to technical questions there were a lot of behavioral questions related to Amazon leadership principles; even from engineers. Looks like they are very serious about this. Overall, everybody was very nice and I actually enjoyed those 6 hours.
