I applied online. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Feb 2011
Interview
Applied online through the local campus career center. Initially was supposed to have an on-campus interview although due to extenuating circumstances, some of these interviews were canceled. Spoke with recruiting and was later scheduled for two phone interviews scheduled. The hiring process consisted of two back-to-back interviews each 45 minutes in length. The first interviewer was straight down to business and asked me some programming questions while the second one took some time to answer any questions I had about the company before asking me some programming as well as design and behavioral questions. Both interviewers were courteous and gave me the time I needed to solve the presented problems. One piece of advice I would offer is to verbalize your thoughts when attempting to solve a problem so that the interviewers can get a feel for your thought process and nudge you in the right direction if you are a little stumped on a particular question.

Interview
I went to school's career fair where amazon held interviews. The whole interview took 90 minutes with 2 interviewers. The questions are pretty straightforward. The interviewers are quite nice and professional. I was given a lot of hints, but I misunderstood one of the hints and screwed up that question.
