Amazon Senior Product Manager interview questions

I'd like to respect the NDA that I signed so I can't dispense the details. However I can give an overview of the interview structure. Phone Call 1 - Screening with the recruiter Phone Call 2 - 45 mins interview with a very level Manager Phone Call 3 - 45 mins interview with another manager Flown to Seattle after 2 weeks. 6 back to back interview of 45 mins each. Get an email from the Recruiter, that they had "very positive" feedback from the team, and that they want to discuss the next steps. I call them, and am told that the entire team had very positive feedback but they had new developments. Thus, they are going ahead with an internal applicant. Positives: Loved the whole interview process. Right from the interviews till my logistics of travel - everything was handled in a very professional manner. Loved the interview panel - extremely pumped up and smart Amazonians. I was asked me a lot of brain teasing questions. Negatives: Be very careful. After all the energy you spend in going through interviews, the travels and so on, you might have gotten all the positive feedback form the interview panel, yet they might say they cant hire you because of "other" reasons.
