    Application

    I applied online. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in January 2017.

    Interview

    About 2-3 weeks after applying I was emailed a link to do an assessment that was about an hour long. It included 7 easy debugging questions, and a couple dozen logic/pattern questions which were a little more challenging. A week after completing that, I received an email to do a programming assessment. This one consisted of two programming challenges, one on data types and one on algorithms. A few days after completing that I received another email to schedule a phone interview. The interviewer called me on the scheduled time and the interview was about an hour long. 10 minutes was questions about my past projects and school history. 45 minutes were spent on a technical challenge. And 5 minutes at the end was available for me to ask questions.

    Overall, I was dissapointed by the lack of human contact and the text editor they used online for the phone interview was very buggy.

    Interview Questions

    • Out of respect for Amazon, I won't share specifics, but the question in the interview came down to finding a recursive solution to the problem presented.   Answer Question

    Application

    I applied online. The process took 2 weeks. I interviewed at Amazon in January 2017.

    Interview

    I applied on the careers website in early October. I didn't hear anything until early January when I was given a 20 minute code debugging assessment and 30 minute logical reasoning test. The debugging was really easy. You just had to fix the mistake. The logical reasoning was alright. Not too bad but you have to be quick. Two days after I finished it, I was given a 70 minute coding assessment and 10 minute work style assessment. The coding assessment had 2 problems and was pretty simple. The work style assessment consisted of putting agree/disagree/etc. for statements. Three days after finishing that, I received my offer. I never had a phone interview or anything.

    Application

    I applied through an employee referral. The process took 3+ months. I interviewed at Amazon (New York, NY).

    Interview

    Applied through employee referral. Few weeks later got the 1st online test, then a week later got the 2nd online test (work simulation/ coding). Thought I failed the coding part but was fairly surprised when they asked to schedule a video interview two weeks later.

    The video interview was short, only 30 min. The interviewer mainly just wanted to about the company and any questions I had about Amazon. We went over one of my solutions for the coding portion of the 2nd online assignment and after some questions he said they would get back to me within the week about how to proceed.

    I thought this meant onsite if i passed, however to my surprise I received an offer three days later.
