Amazon Software Engineer Intern interview questions

I applied during the Spring Employment Opportunities Conference of our university, and got the on-campus interview. It was 2 consecutive interviews, 45 minutes for each. 1-2 questions for each interview, depend on how fast you can finish the first problem. Write the code on white board. non-technical questions: how did you solve it when you have conflicts with teammates? Tell about one of the open-ended projects that you have done.

I initially got contacted for a full time but then requested an interview for an internship as i graduate in 2015. I had two 45 minute phone interview, pretty standard questions, Given a log of users visit to a site for a day, how would you find returning users given the log visit for another day. I can't remember other questions but they all focused on knowing how to use data structures, runtime and design. I got and acceptance letter two weeks later.
