Amazon Software Development Engineer interview questions

Was contacted by university recruiter requesting an onsite interview. Did not complete any phone screens prior. I think this was either from me handing in my resume at my university's career fair, or just plain luck. Flew me out one week later to Seattle, WA for a day of onsite interviews. Interview structure was different than normal -- work in a group with other interviewees to complete a project. It was a group collaboration project, but coding was done individually. Throughout the entire day, we were to code our individual parts while getting selected for 1 on 1 interviews (twice) during the day. The 1 on 1 interviews were very slack, they just asked what we were coding for that project, nothing in-depth technical. Got a good hotel, good reimbursements, had a good time in Seattle. Got the offer 8 days later. Probably will take it.
