I applied through an employee referral. The process took 2 weeks. I interviewed at Google (New York, NY) in Oct 2015
Interview
I was contacted by a recruiter after a referral. I had one phone screen and then a take home challenge. The phone screen consisted of some very basic stats and CS questions. This was followed by a detailed take home challenge where I had to analyze a data set on google's internal data.
It was all good, the interviewer was very nice. Technical questions were a bit challenging but overall it was good. The hiring manager was looking for some hands on experience
Back to back interview.
[1]. Mainly ask ML concepts, e.g., how to develop a classifer for youtube video; they will also ask some statistical concepts
[2] Coding for both python and sql
Applied at PhD level so I had two back to back technical interviews. One all stats concepts and the other talking over a hypothetical experiment design and walking through my thought process.
