Google Software Engineer interview questions

I first had a phone screen interview. After this, I was asked to come onsite for further interviews. I had 4 whiteboard and 1 lunch interview with the Youtube team. After this, I was told that my application is going through the Hiring Committee. Hiring committee asked my HR to find a team for me before giving any decision. I then had two phone interviews with different teams in Android. I informed my HR that I am interested in the first team. Next day, HR emailed me and said that this team no longer has an open position. I again went through the same process. This time, platform team was interested in talking to me. I gave 2 phone interviews wherein they made me write code. After their feedback, I was put through the Hiring committee again and this time I got a thumbs up from them. 1 week after that I was put through executive committee and got my offer. I had 7 other offers and my HR asked me about all of them before putting me through executive review. They gave me more than any other company I had offer from.
