Amazon Software Development Engineer interview questions

Talked to them at a campus event and sent in an application online. After about a month got invited to an on site interview. Unfortunately, got the rejection about a week later.

Got contacted by a recruiter. They flew me out the next week to do a group interview where I coded on a three piece project. Each individual in the team works on a portion of the project, but you work as a team to develop the entire concept of the program. Total of 7 hours with about 5 hours of interviewing. Meanwhile a group of 4 amazon employees are watching you and eventually you get a one-on-one interview to discuss the current implementation of your code.
