Amazon Sr Project Manager interview questions

Amazon likes to put candidates in small little rooms (what I think of as interrogation rooms) and grill them all day. (In reality, these are their standard meeting rooms.) Amazon is exceedingly data-centric, and for positions like the one I was interviewing, it is important, but for a Product Management position, I think it's stressed too heavily. I was interviewed by developers about algorithms at one point!

Was contacted initially by HR. HR was very friendly and responded promptly to any of my inquiries during the interview process. I was asked some basic questions by HR, then had a phone interview scheduled with the hiring manager. Unfortunately my phone interview had to be rescheduled a couple of times over a month without much notice. After I had the interview, the hiring manager felt I was a better fit for another position, I was referred to another hiring manager. I had a phone interview with that hiring manager, and think they were looking for someone a little more technical.
