Amazon Intern interview questions

The interview start with a phone call, then they invite you to formal interview after the phone call one, they ask you more on the role and more on yourself.

Pretty smooth process, received OA, was allowed to split that into multiple parts. Phone interview/technical interviewer was friendly, talked about previous projects for a little bit before moving on to actual technical portion. I didn't solve all the problems in OA but still got the phone interview.
