Amazon SDE 1 interview questions

We were taken to a hall to write the interview answers. I didn't pass the test so didn't qualify for the next round. There were many people in the room writing the test with me.

It was a five round process. I made till the fourth round. They were programming questions. Last round was HR, which I didn't make to. Good questions, but some interviews seemed disinterested. It went on for around 2 hrs, with each round consisting of questions from different segments of competetive programming.
