Amazon Software Engineer interview questions

I got an interview with Amazon when they had come to my University. We had a short (10 min) screening interview while taking my resume (About string matching if I remember correctly). I also applied for this position through my Uni's career center. The follow up occurred two weeks later and interview dates were scheduled - the interviews were on campus with Amazon employees. There were 4 rounds (each lasting about an hour). the 1st round was a short resume review followed by 30 min of knowledge questions covering C++, memory management, OS concepts and a coding question (on paper). The remaining three rounds were almost purely the coding type questions that Amazon is famous for and an object oriented design question (Hotel management system). The questions asked were very very similar to those that are found in career cup - Anyone who practices those questions will be in a favorable position to tackle this interview as they will almost certainly encounter similar questions during the actual interview.

Got recruited via LinkedIn a few times as I was nearing graduation, then got invited to an all-day group interview in Seattle. It was a lot of fun. Worked on a problem with some team members and had a one-on-one interview in between. Even though Amazon suggested a coding interview book, they didn't ask any coding interview questions, or even any behavioral ones. It's all about the project and the group interaction I'm guessing.
