    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.

    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.

    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
