    Application

    I applied online. The process took 2 weeks. I interviewed at Google (Mountain View, CA) in March 2017.

    Interview

    It was a phone interview. Submitted resume over Google recruit site. As a new graduate I was given an email with some links to study on the scale of the coming interview and a bunch of papers about GFS, bigtable and such stuff.. HR reached out to me in two weeks via email after the resume was sent. She was helpful and responsive. During the phone interview, the interviewer got straight forward to coding without asking anything about the resume. Overall it was a positive experience.

    I applied online. I interviewed at Google.

    Interview

    Took an online quiz that was relatively simple. Then another that was harder.

    Then there were two phone interviews about two questions each.

    Went to Google Mountain View in November and had four interviews. Wasn't too easy.

    Interview

    Had two on-campus interviews and one follow-up phone interview used as "another data point." On campus interviews went okay, I was able to do the problems but it took me a little longer than I should have needed. The follow-up interview went well in my opinion but probably not well enough to compensate for my mediocre performance on the on-campus ones.

    Interview Questions

    • Given two lists A and B containing sorted non-unique integers, return the elements in A but not B and the elements in B but not A.   2 Answers

    Easy Interview

    Application

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

    Interview

    Phone screen followed by an online recorded programming challenge. The programming challenge was pretty easy in my opinion. Maybe that has something to do with why I got hired. I think it was a very fair challenge though. Not like a hazing ritual but a very straightforward problem to code a solution to.

    Interview Questions

    • I don't recall exactly the challenge but you had to code something in a tool that recorded you as you typed. And then they can later review how it went.   1 Answer

    Difficult Interview

    Application

    I applied through an employee referral. The process took 2+ months. I interviewed at Google (Mountain View, CA) in November 2016.

    Interview

    Total process took almost 2 months. One telephonic, followed by the onsite (5 interviews). During this process 5 times recruiters changed. Each time they told me different thing about the reference. Last one said no reference was needed till I'm getting an offer. I took preparation for 1+ month (maths, algorithm, data structures, solving problems from leetcode, glassdoor, reading papers on GFS,map reduce and many more). Interview questions were difficult (as expected from Google) but I solved all of them reasonably fast (from my perspective). 10 days after the interview recruiter told me my data structure/algorithm went well but there were some problem in the coding part of the interview, due to that I was rejected by hiring committee and asked me to reapply in 12 months. This feedback is mostly useless as I code every day at work which are reviewed by peers and I practiced a lot for this interview as well. So I don't know what went wrong in coding part. I don't know if this much time investment worth it or not. I'll probably not reapply in Google.
