Amazon Sr Project Manager interview questions

My biggest complaint is that they did not review the writing sample prior to the interviews. I spent 6 hours on interview calls on Chime. At the end, I was told my writing sample was not good enough. I wasted way too much time. They should have done this prior to the sessions.

It was three round. First round was with Manager, It looked very simple. Second was with hiring manager. It too looked very simple but I did not get a call back from the recruiter for the 3 round
