There were 2 phone interviews (one behavioral and one market selection case). HR seemed overworked with most emails going unanswered when you try to contact them prior to your interviews. As one other interviewee had indicated, the scheduling of the flights happened at the very last moment with no communication in-between leaving you clueless on if you will make it to Seattle that day or not. On site interviews were similar in nature to the phone interviews. The questions were very similar to what is already posted here (how would you go about bringing this product to market, how would you price this product etc). Nothing too difficult if you had prepared for case/behavioral questions. All interviewers except one were very friendly and the interviews were conducted very professionally. You are given sufficient time to ask any questions during each interview and all the folks seemed genuine in their replies. However, based on what I saw on interview day (and based on the number of people I ran into at the hotel), Amazon seems to interview an abnormally high number of folks on-site (even from top 5 b schools) for the product manager position and ding a lot of them. That seemed to indicate a total lack of respect for time for all involved.
