I applied through college or university. The process took 2 days. I interviewed at Amazon
Interview
I'm an MBA candidate. Interviews were held on campus and consisted of two days of interviews (two interviews per day). Those who made it through the first round were called back to return on the second day.
Interview questions [1]
Question 1
Two interviews were strictly problem solving questions, one was a mix of behavioral and problem solving questions, and the third was strictly behavioral questions. For the problem solving questions I was asked "what country should business unit XX expand to," "who will win in tv, apple or google," etc. In each of the questions there was a focus on what data I would need to make my decision. Once I answered this part of the question, I was often asked "what else" would you need. My advice is to just keep throwing ideas out there and not worry about being wrong. I think you need to prove that you can keep up with them and not be intimidated by their style.
