Amazon Software Development Engineer Intern interview questions

The call I got was a follow-up from career fair. In the two back to back interviews, I was asked to write code for string reversal, comparison of two binary trees. Then I was asked to design a OO Traffic system. Then there few questions on data structures like hash map, linked lists and I was also asked few questions on my previous projects. After ten days I got the offer.

I applied online to all the available software engineer positions in Seattle including the inter ones too. I was contacted by a recruiter in a couple weeks vial email. I was scheduled for two technical phone interviews which were completely technical in nature. First interview only had one big coding problem that took all the time of the interview. The second interview had some smaller problems and the coding problem at the last was not that big too. Overall the interviews were not difficult and tricky in nature and I believe I did really well inn them.
