    Average Interview

    Application

    I interviewed at Amazon Lab126 (Cupertino, CA) in April 2014.

    Interview

    Initial communication was great, all in all a very good experience. Technical phone-screens were all as expected. The interview questions were much more heavily design-focused than algorithms focused, probably due to the nature of the position I was applying to. Most of the soft skill questions were reasonable, but some of them sounded like the interviewers were driving at particular answers they were expecting, and it was difficult to gauge what they looking for. The interview would have been rough back when I was younger, but was quite reasonable for a senior level position. All in all, though, it was as good an experience as one could ask for.

    Interview Questions

    • One of the interviewers asked me a design question that was very far afield of my expertise, and I winged it as best I could -- after doing my best with that question, I bowed out of further consideration for that, and he gave me a much more general design question that was a bit of a softball, and I asked him some pointed questions regarding Amazon's distributed design ethos. The fact that the initial question was so far afield of my resume makes one question if that is the point, or if   Answer Question

    Reasons for Declining

    I had more than one offer to consider, and gave notice while debating between the two: my current employer immediately made me a counter-offer I couldn't refuse (significant promotion & raise).

    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 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

    Application

    I applied through a recruiter. I interviewed at Amazon Lab126.

    Interview

    I was contacted by an internal recruiter saying she was really excited by resume and wondered if I was interested. I said sure. It took about a month to set up a tech interview. They guy I talked with seem very left-brained geeky. There were absolutely 0 job specifics -- everything seemed to be "top secret". woooo....

    After my phone screen technical interview ... crickets. no "thanks but no thanks". no nothing...

    Interview Questions

    • Write code to permute a string. I've been programming for 30 years, 20 in games. I have written code to do permutations exactly ... 0 times! It's not all that trivial. I recognized it needed recursion, but I whiffed under the interview pressure. Later looked it up and found he was giving me hints that aren't even in the basic algorithm. I guess I was either unlucky or fortunate (I wasn't at all convinced yet I'd want to work there).   Answer Question
