Amazon Software Developer - Internship interview questions

I talked to someone at a conference and a week later got an email to send him his resume. Some months later I got a coding challenge to complete in a week. It was 20 minutes for like 7 easy debugging problems.

Phone Interview: Talked about resume and basic computer science concept. Then only one coding questions. After the coding question, asked him a few questions about Amazon and his team. The interview lasted for 45 minutes. The interviewer was nice, he cared about time complexity and space complexity most.
