Amazon Software Development Engineer I Intern interview questions

They contacted me via email for the phone interview. The questions asked are all text book questions. Simple. The interview was scheduled for 45 mins. but it went for 1 hour 5 mins. I was surprised that I was not selected even after answering all the questions correctly.

I had a 45 min phone interview with a SDE working for the backend of Amazon cellphone page. It was a nice experience. We first talked about one project that I have listed on my resume. Then he asked me several technical questions and one algorithm design problem. At last we talked about the working environment of Amazon.
