Amazon Program Manager (Non technical) interview questions

Very lengthy process - took almost 2.5 month to reach final round of face to face interview. Ambiguous process - Got shortlisted for multiple positions and was interviewed for them for multiple rounds. This was very confusing and difficult as positioning myself differently for each time was not that easy. Lagging prep / discipline from Amazon Staff - I was called for the final interview to HQ. Here the interview was supposed to be with 4 different people, 2 face to face and 2 on VC. Out of 2 Face to face interviews, one interviewer did not turned up, and on follow up in last minute, interview was conducted by phone. Two other interviews were supposed to be on VC but their VC system did not work and both interviews turned up to be only telephonic. Only last interview went on as planned. Amazon should instigate some discipline to their recruitment process, and if someone is scheduled for interview, they should have the curtsy of already respecting it and conduct the interview as it is planned for. Overall interview process here seems to be very structured with lots of situational questions but In reality it's much immature and unstructured. All situation based questions I have been asked were pretty much standard and are available on internet with ready answers. Sent from my iPhone
