I applied through college or university. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Mar 2013
Interview
I had given my resume to an on campus recruiter and I was called in for an interview. The interview consisted of four half an hour sessions that were a mix of both technical and behavioral. I was interviewing for a business internship and the people who conducted the interview were impressively intelligent and all had their MBA's.
I had two phone interviews each 45 mins. The first round has two questions and it was technical and no behavioral questions. In the second round, I was asked about my work experience, my project. Then I was asked one technical questions which took up the entire 45 mins. The first round was a bit easy and the second round was a difficult one.
