    Software Engineer Interview

    Anonymous Employee in Mountain View, CA (US)
    Accepted Offer
    Positive Experience
    Difficult Interview

    Application

    I applied through an employee referral. The process took 4 weeks. I interviewed at Google (Mountain View, CA (US)) in April 2014.

    Interview

    Direct onsite because I interviewed in the past and did well that time. From the time I sent my resume to interview day: 2 weeks. From interview day to offer over the phone: 2 weeks.

    The syllabus for the interviews is very clear and simple:
    1) Dynamic Programming
    2) Super recursion (permutation, combination,...2^n, m^n, n!...etc. type of program. (NP hard, NP programs)
    3) Probability related programs
    4) Graphs: BFS/DFS are usually enough
    5) All basic data structures from Arrays/Lists to circular queues, BSTs, Hash tables, B-Trees, and Red-Black trees, and all basic algorithms like sorting, binary search, median,...
    6) Problem solving ability at a level similar to TopCoder Division 1, 250 points. If you can consistently solve these, then you are almost sure to get in with 2-weeks brush up.
    7) Review all old interview questions in Glassdoor to get a feel. If you can solve 95% of them at home (including coding them up quickly and testing them out in a debugger + editor setup), you are in good shape.
    8) Practice coding--write often and write a lot. If you can think of a solution, you should be able to code it easily...without much thought.
    9) Very good to have for design interview: distributed systems knowledge and practical experience.
    10) Good understanding of basic discrete math, computer architecture, basic math.
    11) Coursera courses and assignments give a lot of what you need to know.
    12) Note that all the above except the first 2 are useful in "real life" programming too!

    Interview 1:
    Graph related question and super recursion

    Interview 2:
    Design discussion involving a distributed system with writes/reads going on at different sites in parallel.

    Interview 3:
    Array and Tree related questions

    Interview 4:
    Designing a simple class to do something. Not hard, but not easy either. You need to know basic data structures very well to consider different designs and trade-offs.

    Interview 5:
    Dynamic programming,
    Computer architecture and low level perf. enhancement question which requires knowledge of Trees, binary search, etc.

    At the end, I wasn't tired and rather enjoyed the discussions. I think the key was long term preparation and time spent doing topcoder for several years (on and off as I enjoy solving the problems).

    Conclusion: "It's not the best who win the race; it's the best prepared who win it."

    Negotiation

    You can and should negotiate politely. You are in a stronger position if you have another offer, but even otherwise, you should ask for more of every type of payment!

    Easy Interview

    Application

    I applied through college or university. The process took 2 weeks. I interviewed at Google in April 2015.

    Phone interview:
    The Interviewer was late for 20 mins... Ask nothing on my resume.
    Tow questions:
    1) A string consists of ‘0’, ‘1’ and '?'. The question mark can be either '0' or '1'. Find all possible combinations for a string.
    2) Give you a text file, remove duplicated lines.
        Follow up: If the file is very large, general hash map takes too much spaces, come up with a better solution.

    Average Interview

    Interview

    Applied online and a recruiter reached out to schedule two 45 minute phone interviews where we coded on a blank Google document. Seemed like they cared a lot more about learning while doing the problems rather than just getting the problems correct. I then got an email about going to the hiring committee a few weeks later. Then I received the offer about a month after that.

    Difficult Interview

    Application

    I applied through a recruiter. The process took 5 weeks. I interviewed at Google (New York, NY (US)).

    Interview

    The entire hiring and interview process has been amazing.

    Google is a company that has a difficult selection process, they are looking to really get to know who you are and what you can bring to the company.

    My recruiter has guided me through this entire process and helped me to reach my full potential.

    The process consists of several interviews were you will be asked different types of questions to get to know your experiences, problem solving capabilities and thought process.
