Amazon Software Engineer Internship interview questions

They had an on-campus coding test for our college and about 40 people were there taking the coding test online. There were a few behavioral questions, about 7 debugging questions, and 2 programming question. I finished the first question but not the second question. I then moved on to the next round which is an online interview. This was about 2 to 3 weeks after the initial coding test. I had two interviewers, one of them shadowed the main interviewer. They asked a lot of scenario questions of when I work on a project and how I approach it when encountering a difficulty. Then, we proceeded to a few basic programming questions, some algorithmic/data structure question, and one object-oriented problem. It was a relatively easy interview, and I thought I did well but didn't get an offer with no explanation why. The interviewer confirmed a lot of my answer and approach.

I went through two coding challenge interviews. The first was half multiple choice, half debugging. They were pretty simple and straightforward. The second was a bit more challenging but doable if you don't panic.
