Amazon Software Development Engineer interview questions

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.

My school is not one of the schools where Amazon recruits from. I started by going to the Amazon jobs site and applying to all the positions that I thought I was a good fit for. A week or two after I filled out my applications, I got an email from an Amazon recruiter inviting me to an on-site group interview (no phone screens prior to this). They flew me to Seattle, put me in a hotel nearby, and we (the other interviewees and myself) participated in an all-day coding exercise. I cannot discuss the problem that they gave us, but once we finished, we were free to leave. Spent the rest of the evening exploring Seattle, flew back home, and am now waiting for a response from them.
