Amazon Senior Project Manager interview questions

I responded to an online job posting that was somewhat vague but intriguing. Email contact indicating a screening interview. But it was actually with the hiring manager who seemed distracted and unprepared for the interview. Honestly I'm not even sure if I was talking to the right person. In short a strange and unflattering experience for Amazon.

3 rounds, initially 2 rounds over the phone and one in person at Seattle. Phone interviews were straightforward. In person consisted of 5 different 45 mins interviews, all behavioral around Amazons leadership principles.
