I had two back-to-back "hangout" interviews, followed by a third "hangout" interview a week later. They all had the same format: * The first 5 minutes were for the interviewers to introduce themselves and explain how the interview would proceed. *

Onsite interview. 5 rounds: 4 technical and 1 behavioral. Onsite interview at Google Sunnyvale HQ. You would have a 45-minute break at noon. A Googler would lead you to lunch; this is not part of the interview process. I had 2 technical interview

First, get connected with HR. Didn't have an online assessment or phone interview in my case. After a 5-round (4 technical interviews and 1 behavioral interview) onsite interview, I had two more additional interviews.
