Amazon Account Manager interview questions

Had a 45 minutes phone interview with a recruiter, went pretty smooth, she asked me a lot of questions and conducted a short english test. I was surprised to get a rejection email after this phase alone. It's quite frustrating that you don't have the chance to showcase your skills and best qualities in person, and being rejected right on the beggining. I asked the recruiter for a short feedback for what was exactly wrong, because it was rather odd to be rejected after that interview in my opinion. and to my disappoitment, I did not get any answer - even not a premade one. Didn't expect that kind of behaviour from Amazon...
