I applied at a job fair. I was contacted within a week for the position of Software Development Engineer at Amazon Vancouver. There were no recruiter screening interviews. The recruiter got in touch with me over email and scheduled a phone interview. I had to reschedule the interview because I wasn't well the day before the interview. There was no problem with that. They did send a pdf file containing information on what to expect in the interview. Essentially, the document said you should be prepared to answer programming problems, algorithms, data structures, distributed systems, databases, networks and operating systems. The recruiter was nice and prompt in responding to emails and inquiries. However, the phone interview itself was a very unpleasant experience. I don't know what kind of phones were used but I had difficulty in hearing the interviewer and he seemed to get annoyed by it. He ruined my overall experience.
