Amazon Non Software Development Engineer interview questions

There were 2 rounds of interview. First one was a technical interview which had only a single question to answer. I had to explain it from inside out. First the brute force solution and then the most optimal solution. Second round had two questions. Both on medium-hard difficulty. Interviewer were helpful throughout.

Good and interactive, the UI is interactive and provides a competitive environment.The interviewer explains the question well and give proper guidance to solve the question. The round was on time and there was no delay for further round.
