Applied though a refferal. Recruiter mailed me and said that there would be 3 interviews (which now suprises me because most of guys here say that thay had only 2 interviews) and she also specified a number of dates and asked to choose one day where It was suitable for me to have the interviews. And she also said that I could have interviews via Hangouts. Then all three interviews were scheduled. I had three interviews in a row with small pauses in 15 minutes between them. And they were at night because my local time differs from a local time in California. Be ready that having interview via Hangouts in some cases may be not very good idea. It seems like Google employees don't have headsets and instead of this they use embedded webcam microphones. My third interviewer put webcam quite far and because of that I could hardly hear them and had to ask to repeat what he said few times during the interview. First interview was quite good, I coded the task and after that interviewer asked to propose a solution for the case when we can use multiple computers, I resolved it. Second interview was quite good as well, Interviewer asked to code a function that he specified. The third interview, as I said before, wasn't so good - I solved just a half of the problem and probably would have solved the other part if interviewer had better microphone because he tried to give some hints but I just didn't understand what he said. For now I'm waiting for some response but because of the last interview I think that I'm not going to have an offer.
