Software Development Engineer Intern Interview

Anonymous Interview Candidate  in  London, England
Anonymous Interview Candidate in London, England
Application Details

I applied online. The process took 1 week - interviewed at Amazon.com in March 2014.

Interview Details

I applied on their website in November. Had no response until February, when a recruiter contacted me, sending me a link to a Codility test (which was quite difficult). A week after I submitted the test, the recruiter called me to let me know that I passed the test and that they are inviting me to an onsite interview. The interview was difficult, but straightforward. The interviewer was very nice, and gave me hints when I felt that I was stuck.

Interview Questions
  • The technical problem wasn't something very difficult at first sight, but the trick was finding out the most efficient solution, which involved using tries. This solution was not implementable in 45 minutes, so the interviewer asked me to implement a specific part from the solution. There were very few behavioural questions, and nothing unexpected.   Answer Question

    Application Details

    I applied through a recruiter. The process took 3 weeks - interviewed at Amazon.com.

    Interview Details

    Recruiter reached out at the end of November asking to schedule 2 back to back interviews which we set up for the next week. Exactly 2 weeks later (almost to the minute) the recruiter replied with an offer. We set up a phone call to discuss the details of the offer a week later and after that I accepted.

    Interview Questions
    • Interview 1: Started with basic cv chit-chat and discussing projects. Was asked general information (complexity and high level implementation) about data structures you'd expect to find in standard libraries. Continued on to a super simple coding question that was something like reversing a string in place. Then had a longer coding question that was a variant on the subtree sum problem and could be made to run in O(n) time with some preprocessing. Overall not particularly difficult.   Answer Question
    • Interview 2: Like the first interview this one started with basic cv questions and a simple coding question. Then moved onto a longer question that was basically weighted graph search but the edge weights were dynamic. Harder than the first interview but still not too difficult compared to other companies. I'd say about similar in difficulty to google but easier than palantir.   Answer Question
    Negotiation Details
    I don't think internship offers are negotiable but in any case the offer was much higher than I'd expected.

    Software Development Engineer Interview

    Application Details

    I applied through college or university. The process took 4+ weeks - interviewed at Amazon.com in June 2014.

    Interview Details

    The entire process was very enjoyable for me. Before the interview, I was informed on the topics they would ask so I could better prepare myself for it. I had back-to-back interviews with 45 minutes each. The interview didn't delve too much into my past experience and just went straight to the technical questions. I answered 2 questions for each interview. The questions were about data structures and algorithms, if you know the Cracking book pretty well then it should be no problem. The interviewers were nice and guided me with the right directions to answer the questions. I was given an offer a week later and was provided with very detailed information about the internship. Overall it was a very positive interviewing experience for me.

    Interview Questions
    • Very expected questions. For every question, you are expected to explain your approach, step through conceptually, and then write the code, step through the code, and clean up the code. Although questions are not the most difficult, you need to be very accurate and precise with your thought process and code.   Answer Question

    Application Details

    I applied through college or university. The process took 1 week - interviewed at Amazon.com in February 2014.

    Interview Details

    Applied online in January and after 2 month when Amazon hosted a career fair on our campus, got selected for back to back 90 mins interview. 45 mins with each interviewer. Questions are standard questions. If you do problems on UVA online judge, Topcoder or Hackerrank regularly, these type of interview questions should be fairly straightforward to answer.

    Also, as many other big tech companies, just solving the problem is not enough. It's also important that you make sure your thought can be understood by others. Explaining how you come up with a solution with clarity is much more important that just solving all of the problems without saying how you did it.

    There are four questions. 1 focus on math, 1 on building trees, 1 on linkedlist and 1 on string manipulation
    As always, make sure you also understand the complexity and performance of you solution.

    Negotiation Details
    No negotiation. But I think the final offer (final salary) also depends on your performance during the interview.
