Amazon Software Development Engineer interview questions

I applied using the university system and the interview was scheduled through that. There seemed to be some problems with email communication since I would occasionally fail to receive emails that were sent to applicants. There were a lot of interviews on campus (I think they interviewed at least 50 people within 2 days) so everything was well-automated. The format was 2 back-to-back 45 minute 1-1 interviews with developers from different teams. In general, I would recommend brushing up on basic algorithms and also reading up on Amazon services, especially all the web and cloud systems.

I had on site interview marathon consisting of several in person one-to-one interviews with managers and team members and one with HR person. The interview set was set up by the company recruiter over email communication. Every interview had a smal QA session and then I was given one problem to solve and present it in corresponding way.
