    Application Details

    I applied through an employee referral. The process took a weekinterviewed at Amazon.com in September 2014.

    Interview Details

    I submitted my resume and asked a friend (Amazon research scientist) to refer me.
    After a few days, I received an email from a coordinator who set me up a phone interview with an expert.

    The phone interview took about 45 min. He asked "tell me about yourself that is related to the job description." He was looking for a topic or experience to begin a job-related conversation. He asked about one of my researches. It took 15 min and we talked about it. He was knowledgeable and a good listener.

    Application Details

    I applied online. The process took 2 daysinterviewed at Amazon.com in September 2014.

    Interview Details

    The research scientist is more of a statistician role. The interviewer first asked what is the most challenging part in my research projects. But we had some conflicts in a technical part, and I could not convince him somehow... I guess that's the reason I got declined the second day... In the last minute, he asked a Bayesian statistical question, which I answered very fast accurately, but it didn't seem to help a lot.

    Research Scientist Interview

    Application Details

    I applied through an employee referral. The process took 4 weeksinterviewed at Amazon.com in August 2014.

    Interview Details

    Two rounds of phone interviews followed by a one-day on-site interview. Total process took around 4+ weeks. Amazon is efficient in arranging interviews. The hiring decisions are quite random though. The interviewers asked a lot questions about your suggestions on modeling and methodologies in dealing with various specific projects undergoing at Amazon.

    Interview Questions
    • Most questions are relatively open. Some of the interviewers are nice enough to let you know when your answers are wrong and give you hints. The most unexpected question came during the lunch when the manager tossed a system design question while I was eating.   Answer Question

    Research Scientist Interview

    Application Details

    I applied through an employee referral. The process took 3+ weeksinterviewed at Amazon.com in July 2014.

    Interview Details

    Interviewed for the research scientist position for the prime air team not exactly sure which role though. Interview process took around 1 month with 2 phone interviews. Had my first phone interview with a research scientist, asked me some basic questions about quadrotors and PID controllers, and one logic/programming question (how to generate a rand4 from rand2 function which is straight forward and then another question about how to generate rand3 from rand2 which is much more complicated and I struggled to find an answer but I ended up figuring out that it has no perfect solution). I would rate the interview as being great with the pressure decreasing with time. We discussed quadrotors and their aerodynamic principles and the interviewer was super nice and very humble as he said couple times I am not an expert in this particular field so he admitted to the things that he know and the things that he does not know.

    After 3 days the HR arranged for another phone interview, this time the interviewer had a very thick accent and hard to understand, did not introduce his role just his name, and called me 15 minutes late. Again was asked about my resume and details of what I did and do. No aerodynamic questions this time just simple plain PID controller questions. I felt that the interviewer does not have deep understanding of control systems and he kept asking me the same questions over and over again. For example, he asked me what does the I term do in a PID controller like 3 different times. Overall the second interviewer wasn't as friendly as the first one and kinda arrogant.

    Operations Research Scientist – Global Supply Management Interview

    Application Details

    I applied online. The process took 3 weeksinterviewed at Amazon.com.

    Interview Details

    I was contacted for interview around a month and half after I submitted my application online. I had two phone interviews.

    The first interview caught me a bit off guard. The interviewer asked two straight questions related to stochastic process, for which I was ill prepared at all. One is about the optimal stopping time, the other about random sum of random variables. With a bit help from the interviewer, I managed to solve the first one. But I was quick on the second. At the end, the interviewer kindly promised me a second interview.

    So I got my second phone interview, which was focused on math modeling. I thought I did well overall, but got rejection from Amazon one day later. On hindsight, I found out I made a minor mistake by confusing OPL language.

    One phone call from HR in 3 days after applying for the position. One phone interview from the group asked some statistics questions which were good and made sense. The second phone interview also asked statistics questions by whom like a computer science student only want to know answers ...
