Amazon Area Manager I interview questions

Contacted by a recruiter through email. I expressed interest and was told to formally apply for a specific position. The next day I was contacted by another recruiter and asked fill out a profile giving my education, location preferences, previously salary, how many people I've managed, what times I am available to interview, ect. Then I was contacted by a recruiting coordinator who scheduled a phone interview. The interview was completely outside of the times a listed but I adjusted and sent my confirmation email... only to have the interview rescheduled for a week later at the same time. At the 4pm PST interview time (I am on the East Coast 7pm) I dialed into the interview waiting for someone to join the call. After 15 minutes I emailed the coordinator to let her know an interviewer has not joined. 18 minutes later at 4:33 pm PST I finally get a Hello, Hello. Followed by an introduction but never an apology. We both share our background then I am asked a math question followed by 4 situational questions. The whole interview was rushed. I didn't feel good about the math question but did feel good about the the situational questions. The interviewer then said we would stop so I had time to ask questions. At the same time others were joining the call because they must have been scheduled at 5pm PST... which would be fine if my interview wasn't 30 minutes late.
