    Software Development Engineer In Test Interview

    Anonymous Employee
    Anonymous Employee
    Application Details

    I applied through a recruiter – interviewed at Amazon Lab126.

    Interview Details

    All interviews conducted in a room off the main entrance lobby, no tours of work environment. Interviewers could not be specific about technology(s) skills required for the role, or about the product(s) one would work on due to need to avoid disclosing 'secrets'. I did not get an offer, and it would have been difficult to make a decision without more information, or taking a leap of faith.

    RF Systems Engineer Interview

    Application Details

    I applied through college or university – interviewed at Amazon Lab126.

    Interview Details

    Interviews were 1 on 1 with two separate employees from Lab126. First interview was technical and lasted approx 45 minutes. The second interview was also technical but with more an emphasis on problem solving. The first interviewer had a very thick accent and mumbled. They then blamed me when I could not understand their questions. The interviewer nit-picked on things like the color of my resume and the font chosen, and asked trick-questions that were more of a riddle than a real question. It was a very frustrating experience and only made me more flustered for part 2 of the interview.

    Don't Matter At This Point Interview

    Anonymous Employee in Cupertino, CA
    Anonymous Employee in Cupertino, CA
    Application Details

    I applied through a staffing agency. The process took 1+ weekinterviewed at Amazon Lab126 in March 2015.

    Interview Details

    They called me up and wanted me to briefly explain my work history. They then scheduled me for an interview right afterwards. I received an email early the next week with detailed information about my interview orientation. Easy process.

    Interview Questions
    • Very typical behavioral & result-oriented questions. Prepare yourself to think quickly on your previous endeavors and challenges.

      All questions gear towards - What happened? What did you do? What was the result?

      Amazon primarily wants to know the [How did you handle the whole situation?] aspect rather than [Why did you not attain the result?]

      None of the questions were difficult to answer, just like none of the pitches in baseball are hard to hit. They throw a lot of curve balls at you and occasionally a fast ball now-and-then. Prepare to hit anything that comes at you. Seriously, be mindful of your use of words, tone of voice, gestures, etc.

      Overall, I had a great experience with my interviewers, even from the very start of meeting with a friendly team beforehand.

    Senior Software Engineer Interview

    Anonymous Employee
    Anonymous Employee
    Application Details

    I applied online. The process took 2 weeksinterviewed at Amazon Lab126 in January 2015.

    Interview Details

    Applied online. Recruited contacted me with an initial phone screen. Afterwards recruited worked to find a few possible positions that fit my skill set. Recruiter was helpful and friendly, with prompt responses. This was followed with two technical interviews with Amazon engineers. These were conducted over the phone with online shared coding environment. Technical interviews consisted of basic questions on the Java language, design patterns, etc. There were questions on threading and syncronization, and was asked to code several things (more below). Make sure you know the basics of Big-O analysis and practice some algorithm puzzles..
    Overall positive experience. I believe the key is to talk through your thought process, even if stuck on a problem.

    Software Engineer Interview

    Interview Details

    Two phone interviews. Followed by onsite interview. Prepare data structures thoroughly - heaps, trees, linkedlists. Get your string manipulations done too. They test out your problem solving technique. Besides whiteboard coding, they also asked about modeling an airport. One of the interviewers was more intent on stalling and interrupting me than listening to my solution. That was the only harrowing part of the interview.

    Software Development Engineer Interview

    Application Details

    I applied through a recruiter – interviewed at Amazon Lab126 in December 2014.

    Interview Details

    Apply in my campus job fair and got the response from recruiter after 2 months for Group interview.
    During the interview, all the candidates were divided into three-men groups. Each groups had a set of tasks to solve. Teammates were not the competitors at all. It's like a small working environment and I think this kind of interview is really enjoyable. I learned a lot and had lots of fun that day. Proctors were very nice and helpful to give interviewee any kind of useful advises. The interview took a day, so it's better to sleep well last night.

    Interview Questions
    • Any corner cases should be thought as much as possible. When having a question or misunderstanding point in design, don't hesitate to ask your teammate or proctors.   Answer Question

    I applied through an employee referral. The process took 4 weeksinterviewed at Amazon Lab126.

    Interview Details

    Attend the interview almost 3 years ago and was called for an in-house interview after an initial phone screen. Interviewed by 6 people and asked around general questions, how much I know about Amazon Lab126 kindle products. Once the interview is over, I was asked to come back for one more in-house interview for which another 6 people participated in it. Overall, interview is not that hard, but a bit exhaustive.

    Research Scientist Interview

    Anonymous Employee
    Anonymous Employee
    Application Details

    I applied online. The process took 2+ weeksinterviewed at Amazon Lab126 in October 2014.

    Interview Details

    I had two technical phone interviews, about two weeks apart. The first one went pretty poorly, so I was surprised to get called back for a second one. Our phone connection during the first interview was not so good though, so maybe they didn't get in all the questions from the interview script on the first call. Both interviews involved conceptual questions about machine learning paradigms and methods as well as a couple situation-based questions asking to sketch out a solution to a applied task, and a question or two about algorithms. The first interview, but not the second one, included a programming test, but it was really more like a pseudo-coding test, since the interviewer didn't know the language I chose to do it in (Python), and the coding interface doesn't execute the code.

    Application Details

    I applied through other source. The process took 5 weeksinterviewed at Amazon Lab126 in October 2014.

    Interview Details

    A friend that works at Lab126 forwarded my resume to HR and about 3 weeks later they emailed to set up a phone interview that happened about a week after that. The phone interview was about 10 minutes and very professional but a bit frustrating as understandably the HR person did not understand the technical aspects of the position.
