    Senior Software Engineer Interview

    Anonymous Interview Candidate in San Francisco, CA
    No Offer
    Negative Experience
    Difficult Interview

    Application

    I applied through a recruiter. The process took 3+ months. I interviewed at GREE International Entertainment (San Francisco, CA) in January 2015.

    Interview

    One technical phone screen, followed by a 2 hour remote coding test, followed by an all day on-site interview.

    My overall interview experience was exhausting. People were nice, enjoyed answering some of these questions, including the coding test. I was positive about getting an offer but got rejected because they were looking for a principal engineer with more than 5-7 years of experience. That was such a big turn-off for me as they did not make this clear from the beginning at all. And the kind of experience they were looking for, wasn't mentioned anywhere in my resume. I am surprised why they even considered me for this role and invited me over for an all-day interview expecting a level of experience that I clearly didn't have! It was such an exhausting experience and such a waste of both of our time!

    Interview Questions

    • First phone screen: Vector mathematics and algebra basics, like direction of vectors, addition, subtraction and dot product etc   Answer Question
    • Second Phone Screen was a 2 hour coding test. I was asked to solve the famous Island Problem - Given a matrix of 1s and 0s, 1 representing land and 0 representing water, an island represents a cluster of 1s that are connected with 1s in the top, bottom, left and right indexes, and diagonals don't count. I was asked to submit a working code to count the number of islands in the given matrix   1 Answer
    • On-Site Interviews: I had in total 5 people interviewing me back to back, without any breaks in between. It also included a 90 minute coding test similar to the remote coding test. I had to produce a working code to implement a series of encoding functions such as left shift, right shift, flip etc of a matrix of characters in the keyboard. And it needs to run for a given set of test cases.

      Topics I was asked in the interviews are the following:
      1. Questions on C#, design patters, interfaces Vs Abstract classes, partial classes etc
      2. Deep knowledge on maths and trigonometry: Sin, Cos, formula for dot product, cross product including derivations, determinants of matrices, and much more in-depth knowledge on vector algebra.
      3. Some basic questions on Unity game engine such as game objects, transforms, parenting of model imports etc
      4. Behavioural questions - where do you want to see yourself in 5 years, what style of career do you want to carve for yourself, etc   Answer Question

    Application

    I applied through an employee referral. The process took 2 weeks. I interviewed at GREE International Entertainment (San Francisco, CA) in August 2012.

    Interview

    I talked to a Lead Engineer for about 45 minutes. Then I was given a coding test for an hour and a half. Afterwards, we went over the code, all seemed well and the interview continued. I met with 3 or 4 pairs of engineers who proceeded to ask questions and gave me white board problems.

    Towards the end of the interview the VP of Engineering showed me around the office.
