One round with HR for a general resume review. One round of coding, which was a phone screen. Four back-to-back rounds, including three coding interviews and one Googliness round.

Tell me about yourself. Why did you apply to our company? What are your weaknesses? What are your strengths? Brain teasers. Whiteboard questions. On a scale of 1-10, how likely are you to suggest?

Very good environment. Lots of coding. Went through phone screening and then in-person interview. Simple process, but yet a good discussion with the whole team of engineers, manager, and vice president.
