Amazon Intern Software Developer interview questions

I was initially contacted via email. They set up two forty-five minute interviews with me. Both interviewers began by asking me to describe a project I had worked on that I enjoyed or was proud of before moving on to more technical questions.

Applied Online. Got a reply by email asking to schedule phone interview. Phone interview was two 45 minute sessions with 2 interviewers respectively. Was asked basic data structure questions like arrays stacks queues O(n) .For ex: what is an array. Then was asked to write codes to traverse an array in O(n). and then traversing circular list in O(n).
