Amazon Senior Project Manager interview questions

The call itself was strange. I asked questions about the product, who was involved in the past, the current status, who would be involved in the future, how the interviewer imagined it would evolve, the existing challenges, how much work had been done on the business case, how far technical development had progressed, etc. The interviewer stated they had primary responsibility for the product currently, and answered my questions--but it was clear that their thoughts on both the business case, the product itself, and how he was going to allocate his existing development resources was actively evolving during the call. He was clarifying his thoughts and plans based on our conversation. It was also clear that I was merely serving as a facilitator, not really being interviewed. The interviewer was taking the opportunity to put the product roadmap and current plan through it's paces.
