Amazon Technical Programme Manager interview questions

The process consisted of 3 phone interviews and an all day onsite interview with multiple employees. The onsite interviews were pretty standard with the exception of interviews with developers. There is an expectation that PM's are highly technical which is fair, but the developers were not particularly good interviewers with questions which tended to be rather obtuse. Even when setting up a complicated scenario, I have an expectation for clarity. Unfortunately, this makes it challenging for an interviewee to respond effectively.
