Was referred by a friend. Had a phone screen, and multiple recruiters reached out after that over a few weeks. Finally, I had another phone screen, and was told to work on a sample design problem. Submitted the design problem, and was asked to come to the MV campus for a full day interview. The day started with me giving an hour-long presentation on the design problem and my portfolio. I then spoke with 9 employees at one-on-one interviews. Lunch was with an employee to answer questions, and was not an interview. Overall it was a good experience: people I spoke to were interesting and engaged, and my recruiter was friendly and helpful. Complaints were that it seemed to take Google a long time to get their process together - originally 5 recruiters were contacting me all at once, seemingly at different Google locations/teams. Also, there was little ability to apply for a particular role, with applications becoming "general" once accepted.
