Amazon Developer interview questions

This was an unusual situation. The interviewer was eating something during the interview. I felt very uncomfortable and wanted to leave the interview immediately. It was my first time experiencing something like this. I really can't understand how some people can come to places with such disrespect.

OA, not very hard. I think the difficulty level is around medium level in leetcode. Most people can do it if they have fully prepared. I did not prepare well so I failed the OA, but it is doable for many people. The second round interview might be harder, but I failed in the OA, so not very sure.
