    QA Engineer Interview

    Anonymous Employee

    Negative Experience
    Difficult Interview

    Application

    The process took 1 day. I interviewed at Amazon Lab126 in August 2011.

    Interview

    First, he didnt even read my resume to ask me anything related to it. He was the head of QA and seemed like he was stuck up and anything good you said was irrelevant. He only focused on the one question I got wrong and wouldnt move on until I gave him some kind of answer for it. He seemed like he had a cocky attitude. I almost was arguing with him at one point.

    Positive Experience
    Difficult Interview

    Application

    I applied online. The process took 4 weeks. I interviewed at Amazon Lab126 (Cupertino, CA) in October 2011.

    Interview

    I was contacted by recruiter for phone interview . It being Amazon subsidiary has a flavour of amazon that whether you are selected or not , you get the results on time or not but interview will definitely be an enriching experience. It started from few common questions but than interviewer would dig into small nitty gitty details about your projects and would test knowledge on those topics. He was randomly reading the resume and would pick up a line and start questioning, be sure to read and imagine what question can arise from each and every word. It was one interview where I would say that interview questions could be expected from any project irrespective of relation to position to test depth.

    Difficult Interview

    Application

    I applied through other source. The process took 3 weeks. I interviewed at Amazon Lab126 (Cupertino, CA) in July 2010.

    Interview

    At least 1 phone interview about past experience and some coding interview questions. One or two site interviews with about 4 engineers for technical questions and one bar raiser. The bar raiser is an experienced one but sometime they are not from the same field that you are applying for. Questions can be anything. There are some interview guidelines, but most of the time engineers do not learn the guidelines. The second onsite interview most of the time is to see the managers and directors level, but sometime also has some technical questions.

    Interview Questions

    • In my field, ask more about bit field, linked list and hardware debugging skill, like i2c spec, but the most difficult one is to find all errors in a function.   Answer Question

    Negotiation

    I was looking badly for the job, so there is no negotiation

    Difficult Interview

    Application

    I applied through college or university. The process took 4+ weeks. I interviewed at Amazon Lab126 in February 2014.

    Interview

    On-site interviews: Technical rounds The technical interviews were interesting and challenging. Interviewers were forthright. Phone interview: Team matching HR follow-up procedure and phone interview was sloppy I appear to have lost out in this round. And I don't know how to overcome that, given the company's super secret policy about what they do!

    Senior Software Development Engineer Interview

    Neutral Experience
    Difficult Interview

    Application

    I applied through an employee referral. The process took 5 days. I interviewed at Amazon Lab126 (Sunnyvale, CA) in November 2013.

    Interview

    Applied through a recruiter (although I was referred by a friend), spoke to them over the phone and got invited to an on-site interview. It was a full-day interview, I met with four technical interviewers, the recruiter and the hiring manager who took me to lunch. It was all in schedule and fairly well organized.

    Interview Questions

    • A couple of questions on extracting bits from a bit stream, a couple of higher level questions on an actual embedded programming problem. There was the usual simple "algorithmic" question where the solution is to either sort the data or put it into a hash map. The bar-raiser technical interviewer asked a few fairly meaningless "tell me about a hard technical problem you solved, etc."-type questions - these are a mandatory part of the Amazon interview process and the whole conversation felt somewhat meaningless. Overall I enjoyed meeting with the SDEs much more than with the bar-raiser.   1 Answer

    Difficult Interview

    Application

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

    Interview

    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.
