Amazon Sr Project Manager interview questions

4 phone interviews with HR, Manager, 2 peers. One entire day spent at main office with 7 in person interviews. Manager, and other senior team members who I would be working with and one VP. Each about 45 minutes to 1 hour. No questions about my background or experience. Each person had about 4 situational questions to ask. I thought some were odd. Some required math skills. They were friendly but it was intense. I walked away with absolutely no indication of how I did or if the answers were what they wanted to hear. The surroundings were modest and not very well kept. I expected the offices to be nicer. Perhaps when they move to their new headquarters in a year or two things will improve.

The people I talked to are smart. The onsite interview was quite exhausting. I talked to 6 people within 4.5 hours. Interview still went on over lunch. Some of the interview questions were tough and hard to prepare in advance as they asked for my opinions on product/marketing strategies or my thought process in analyzing data for business decisions when I only had a few seconds to think.
