Amazon Product Manager interview questions

I was referred to Recruiting by an employee whom I had been introduced to by a mutual industry contact. Recruiting contacted me via email to setup a 30 minute screening interview, to be conducted over the telephone by a current team member. The screening interview was pretty basic, focusing on why I was interested in the position and how my experience was relevant. Afterwards, the company went completely dark. After 3 weeks I sent Recruiting an email asking about status. Another week went by before I finally got a response apologizing for the delays. A couple days later I was notified that I would indeed be asked to participate in a formal, onsite interview. After the date for my onsite interview had been confirmed (one week out), I was sent a situational interview question in email and asked to submit a written response (2-4 pages) prior to my interview. I had heard that writing and white papers were a big part of how the company goes about its business. It wasn't difficult, I just wasn't expecting to have to submit anything. The afternoon before my scheduled onsite interview I received my detailed itinerary for the day - seven 45min - 1hr long interviews!!! The interviewers consisted of the hiring manager, the hiring manager's manager, a recruiter, several x-org peers with whom you would be collaborating with, and an individual who had nothing to do with the specific role; who was really there to assess your potential to be successful in other parts of the company. As for the interviews themselves - every question I was asked was situation-based and was rooted in one of the company's 14 management principles highlighted on their career site. Be sure to review these ahead of time and come prepared to provide an example from your work experience for each. I was a bit surprised that I was not asked a single question about my knowledge of the subject matter area related to this position or my experience doing the exact same work at another company. It was really all about fit and culture. Which I apparently didn't align with, because, in spite my experience in the area, I was not offered the position. When I asked the recruiter for feedback, I just got a terse response stating the recruiter didn't get any feedback from the team. Done, end of process.
