Amazon Software Development Engineer SDE Intern interview questions

Applied for the position via my school's career services site. Nearly 4 months later received a request to complete two phone interviews. After scheduling the interview, I was never called then received another email to reschedule the next month. The interviewers are generally very helpful, guiding you along the write track as you answer - the first began by telling me a bit about the company and his position specifically. Be prepared to talk about your past experience, as well as answer questions about fundamental OO concepts and data structures. I was given one programming assignment in the first interview and another in the second, the second problem a slight variation of the first - be prepared to dictate your code over the phone (must be syntax-correct). I would suggest practicing by writing code on a notepad/paper instead of using an IDE. I would suggest reviewing data structures, algorithm analysis (you will be expected to analyze the time/space complexity of the functions you write). Received a response 1 week post-interview.
