Amazon Software Engineer/In Test interview questions

The phone interview I had at Amazon was unlike any other I've had. First off, the company has employees who have very strong accents conduct phone interviews. I had to ask the interviewer to repeat what he said several times. The questions themselves were hard enough and not fully understanding the person made it even tougher. That appearently put him in a bad mood and he became rude to me over the phone and spoke in a very unprofessional manner.
