Amazon Software Engineer Intern interview questions

I applied online in Jan 2014. Received an email from recruiter about setting up two phone interviews, each of 45 minute length. The recruiter was supposed to send me a follow up email about which areas the questions will cover etc. but it was sent after the first interview started. The interviews were back to back with 15 minute break between them. The questions were purely technical and only one of the interviewers asked about why I would like to work in Amazon, I think it was more to do with starting a conversation than taking any notes from my answers. Both interviewers for the first 10 minutes asked questions on some basic algorithms, their complexities and Maps etc.
