    Average Interview

    Application

    I applied through an employee referral. The process took 3+ months. I interviewed at Amazon.

    Interview

    2 phone screens, 1 after the other. Each takes an hour. They didn't ask any behavioral questions, not even about my projects or resume, was all technical questions. Interviewers were friendly and helpful. I guess each interviewer has their own style, 1 asked just prob&stats, the other only network design type questions.

    Average Interview

    Application

    I applied online. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in August 2016.

    Interview

    Applied online. I had one phone interview. Asked about very general questions related to data science. No coding session. After that, they invited me for an onsite interview. I was bit surprised because I heard they go through at least two phone screens before the onsite interview.

    Interview Questions

    • I have an academic background and I am trying to move to industry. They asked multiple times why I am switching to industry.

      I also got a lot of non-data science questions, such as basic algorithms questions (sorting, binary trees, time complexity, etc). So it is a good idea to prepare for both.

      They gave a scenario and ask me to tell a story from my experience that resembles that scenario (these are related to Amazon leadership skills).

    Average Interview

    Application

    I applied through an employee referral. The process took 1 day. I interviewed at Amazon (Orlando, FL) in July 2016.

    Interview

    The interviewer is very nice. He would like to give you a hint if you ecountered some troubles. However, there are too many technical questions, which make the pace of interview too fast for me. The interviewer first asked some questions about me research, including some details and clarification some concepts. Then he asked several questions on basic statistics concepts. These concepts need to be interpretted to non statisticians. The questions gradually became complex.

    Difficult Interview

    Application

    I applied through college or university. The process took 2 weeks. I interviewed at Amazon in March 2016.

    Interview

    Contact one of the researchers in the team and put me in contact with the recruiter. No phone screenings. The onsite consisted of a one hour talk, plus 4 1-hour one on ones with scientists, engineers and a product manager. I had lunch with head of department, who was super nice. Sadly, you don't get to know what the project is about until you start working at Amazon, the project is secret also within the company, so you might not be able to tell other Amazonians.

    • Explain your research, how did you solve things, how could it be improved, etc.   Answer Question
