Amazon Technical Support Engineer interview questions

I was contacted by an Amazon recruiter. They were overwhelming enthusiastic about my resume and asked if I was still interested in applying. I filled out a preliminary set of questions that seemed to fit there mold. I was then setup with a virtual interview with preselected questions and no real person doing the interview. It was very odd and the questions were all over the place. You had 3 minutes to answer each question. The recruiter told me the most they could pay was $50000 but Glassdoor specified up to $74000. No follow up in the defined time. I had to contact the recruiter.

First of all, there is some basic technical assessment by web based and then phone interview. it takes 40 - 50 min. they just started to ask technical skills. there was no personal questions ex) tell me about your self.
