Amazon Software Development Engineer I (SDE I) interview questions

It went on for 30 min. For the first 15 min I was asked to explain the approach for my 2 programs that I had written in the OA round, followed by modification questions. The next 10 minutes or so the interviewer explained to me about Amazon, how the projects are and how everything works. And in the last I got to ask questions about Amazon to the interviewer.
