    Application

    I applied through college or university. The process took 3 weeksinterviewed at Amazon.com.

    Interview

    Two on campus interviews that were on the same day. Each was one on one with an engineer from some team at Amazon. The dress code was very casual and the engineers I spoke with were very friendly and easy to talk to. Each asked one question first that was technical and I solved it on a whiteboard and then we spoke generally about the company and my own background.

    Interview

    First half an hour of the interview was about my projects and research. In the last 15 minutes or so, I was asked to code. Interviewer was very friendly but sounded busy. Once he was convinced that I knew what I was talking about, he was eager to finish.

    I applied through college or university – interviewed at Amazon.com.

    Interview

    My interview was held on my university's campus. The process was basically two back-to-back 45 minute interviews. Both interviews had a behavioral portion on the first five minutes. The rest of was technical. The first interview dealt more with providing an algorithm to solve a problem, and analyzing the runtime complexity of the algorithm. The second interview was more focused on object oriented and design pattern questions. The interview was a overall a positive experience as my interviewers tried to provide a comfortable setting and the questions were not particularly out of the ordinary.

    Average Interview

    Application

    I applied through an employee referral. The process took 4+ weeksinterviewed at Amazon.com (Columbus, OH) in March 2015.

    Interview

    Ask someone at Amazon to refer me. Got an invitation to online assessment. Then I had two technical interviews. The interviewers are quite friendly. I guess because they hire a lot of students, so the process takes me nearly a month. For the online assessment, I don't know how much it weigh in the overall evaluation, I actually screw it up cause I only answer like 3 questions out of 7. But I was lucky enough to get the phone interview and did well on the interviews, so I get an offer.

Then he asked me several technical questions and one algorithm design problem. At last we talked about the working environment of Amazon.

    Application

    I applied through college or university – interviewed at Amazon.com.

    Interview

    Submitted my resume during college career fair, heard back about two months later over email requesting an on campus interview. Two 45 minute interviews each with 1 coding question. First guy was talkative and explained what he does at Amazon, the second guy was straight to business and barely spoke. Both were friendly, just the second interviewer seemed like he did not want to be there. I prepared a lot in the prior weeks using the cracking the coding interview book, but honestly the questions were simpler than expected. My problem was that I misinterpreted the question a few times and tried to over complicate things (the coding interview book had much more difficult questions). It has been a week since the interview and still waiting to hear back.

    Application

    I applied through a recruiter. The process took 3+ weeksinterviewed at Amazon.com in February 2015.

    Interview

    I'm posting this mostly because I had a pretty unconventional interview process. An Amazon recruiter reached out to see if I was interested in applying and, after I submitted my resume and personal information, she set me up with a 30 minute online evaluation (an AMCAT). From what I've gathered, this is more of a preliminary screening before passing a candidate onto the phone calls; however, after passing the test, I was given only one technical interview phone call. The call lasted about an hour and only consisted of technical questions. The engineer on the other end only asked what language I was most familiar with after commenting on the number of languages listed on my resume. This was the extent of any and all personal questions I was asked, as the remainder of the phone call was technical. The interviewer was very easy to talk to and I actually enjoyed working out the solutions to his questions. About a week and a half later I was given an offer. All in all, my experience was pretty weird since it lacked both personal questions and the usual second technical interview phone call. tl;dr - Even if your interview process is unconventional, just go with it.

    It was enlightening. They asked coding specific questions, and asked some questions about projects I'd been involved with. They seemed kind of disorganized since they forgot to give me an NDA to sign.
