Amazon Software Development Engineer interview questions

Multiple phone interviews followed by day long on-site interview battery. The in house recruiting person was very professional and although it is a long process all communication was clear and on-time. As I have only done the first telephone interview. It was purely technical in nature. Write code on internet, answer follow up questions on the code. Describe most important project you have done.

I was applying for this position through the campus job hunting website. There were four rounds of interviews, all about programming and it is the only facet that the recruiters are caring about. Since it was a on-campus interview, the whole process was only two days.
