Google Interaction Designer interview questions

An employee referred me to a recruiter and I was selected for a phone interview. The phone interview was 45 minutes in length. I'm not really sure what else to say about my experience.

Got referred by a friend of mine who works at Google. A recruiter was in touch at first, put me on a phone screen. Call went well, got invited to onsite afterwards. The onsite interview contains a portfolio session followed by multiple 1:1 interviews. After the interview, I had another follow-up phone interview with a senior interviewer the next week. Google extended me an offer the next week. Folks at Google are all friendly and willing to answer all my questions I had during the interview. I am joining them in two weeks. Hello Google!
