Amazon Programa manager sr interview questions

I went through the interview process for four different positions. Each process was essentially identical, though just one Onsite was required in Seattle. First, HR screening call. Second, hiring manager call in STAR format. Third, a team member interview in STAR format. Fourth, a set of Onsite interviews in Seattle (all four individual interviews in STAR format), including one with a bar raiser.

I applied online for a position in Seattle, WA. An Amazon recruiter contacted me and told me that she was going to submit me to the hiring manager. A week later I received an invite for a telephone interview asking for my best times to receive a 1-hour call. Once I submitted that information I received another email stating that I had an interview appointment with guy1 on a specific date and time. One day before the interview I received an email that stated that guy1 couldn't make it and he would be replaced by another person (guy2). During the call guy 2 divulged that he was not a part of the team that I had applied for and was in a pool of interviewers and lived in New York City. I waited 1 1/2 weeks after the interview and didn't hear a single word back and then I emailed the recruiter to ask if I was eliminated from the selection process. She called me about three hours later and said that they didn't feel that I was a good fit for the role but they had this other role in the same group that she wanted me to consider. I told her ok in the call and then she started talking about flying me to Seattle. I thought this was a bit hasty because I had not even spoke with the hiring manager and I am getting a face to face interview. I live in Dallas, TX and they flew me to Seattle, paid for my hotel, and I was there with bells on to interview for this job. It was a very long day with seven one hour interviews. They saved the hiring manager for the second to the last interview. I was exhausted by then and was loosing my voice but keep my composure to give them a great interview. Afterwards, I flew back to Dallas and the recruiter emailed me straight away to inform me I was not selected. In reflection, it seemed very unfair. They were too quick to pull the trigger for a face to face interview of me for a role where I was never interviewed by anyone from the team or the hiring manager. Two weeks later I saw another Sr. Program Manager’s position on a website and it was in Austin, TX which is only 200 miles away instead of Seattle, WA. I applied for that position and received a note from the recruiter that said "Once you have had a face to face interview with Amazon, and you are not selected, you are barred from the selection process for two years” I feel that is the most discriminatory thing that I have ever heard. What if the hiring manager in Austin, TX would have taken the time to get to know me and found that I was better qualified than any of the candidates that had applied? I feel like I was wronged by these people.
