The interview process was fairly average. A number of one on one interviews followed by a skills test for 1 hour - I wouldn't say any of it was particularly difficult.
I was more put off by the Googler at the front desk! In waiting for my coordinator, I decided to make conversation by asking how many floors in the building were Google-owned. Apparently, that was way too nosy of a question! He rudely answered "Well, I know, but I can't tell you because you're not a Googler." Ok... I almost walked out then but decided to follow through with the interviews anyway. I did not get an offer and like all Google interviews, I got zero feedback, which is incredibly disappointing given I took off time and flew across the country. At the end of the day, I am happy with the outcome - that Googler needs a bit of an attitude adjustment!
