Sent in an application October 2017. Heard back fairly quickly. Phone interview at the beginning of November. 2 weeks later I received an email about an onsite. Flew out to SF December 1. 4 - 45 minute interviews both technical (coding) and hypothetical and behavioral questions. 1 non-formal lunch. Still waiting to hear back with results of onsite, going on 6+ weeks. Would recommend applying months in advance.

I applied online. After 4 days, I got a chance to interview at google. I had a phone call with the recruiter, which is mainly about what the interview procedures would be like. The recruiter then settled up a phone interview for me. The phone interview is 1 hour long. At the first 5 minutes, we both introduced ourselves. Then I was asked some statistical and coding questions for next 40 minutes. The rest 15 minutes was about asking questions to the interviewer.
