Amazon Program Manager interview questions

A totally uninterested Hiring manager interview. The interviewer called 5 mins before the scheduled interview time, which was uncalled for. And immediately after the hello, the interviewer asked if there are any questions about the position. no introduction, nothing. I have given so many interviews and this has never happened. The interviewer has my profile, a decision could’ve been made based on that. But asking for 5 time slots over next two weeks, scheduling an interview and to be totally uninterested in totally unprofessional. On the other hand, the HR interview was well structured and handled. The interview with the Hiring manager was a disaster. Amazon needs better people to represent them during the interviews.
