Amazon Area Manager I interview questions

First I had a phone interview and an online test, and then I was invited to interview in person. The overall interview process was short and unorganized. I was put into a group with about 6 other candidates, and we all did a math question very similar to the one in the packet. Then, we were split up and assigned to 2 random interviewers. My interviewers knew practically nothing about the position, and weren't even able to answer my questions. Also, the interview process was very unfair. Some candidates met with interviewers that gave them easy questions, while others met with people that gave them trick questions. In order to make the process fair, each person should interview with the same people. I was highly disappointed in the professionalism of Amazon, and I would never want to work for such a company.
