Amazon Graduate Engineer interview questions

Applied online and received a confirmation email telling me they will look over my application. - 1 week later I received an email saying I was into Phase 1 of the interview process, and they gave me a link to a coding debug challenges. The challenge consisted of 6 Java Applications, and the compiler throws an error when compiling, find and fix the error. It was rather simple and got 6/6 within 30 minutes. - 1 week later I received an email telling me I did great in phase 1 and they prompted me to carry onto Phase 2, which is another java coding challenge. The challenge consisted of 2 coding questions that had to be completed within 1 hour. - Around 6 days later I received an email telling me I am not knowledgable enough to enter the next phase which I'm guessing is a F2F interview. Phase 1 is pretty simple, you should be able to pass it with the basic symbol and notation coding knowledge. My advice to anyone getting ready for this interview would be to read: "Breaking the Coding Interview" and attempt all of the difficult questions. College exams would not have prepared you for these types of questions!
