Amazon Software Engineer interview questions

After I submitted my resume in university career fair. I got 2 round on campus interview. All techinical questions, actually not about the project experience too much. The first round is by AMS manager who seems pretty nice and interested in large scale computing. The interview went nice and I need to write code on a paper briefly about my solution. Second round is by 3 interviews together,45 min each with an engineer. The problems are like link list, priority queue, binary search tree and almost all has been mentioned somehow in career cup or so. Take a look at the interview preparation website is a great help. They seems like the free and open culture in Amazon and they have great passion about their job. Very nice.
