On site at Menlo Park: A set of 3 interviews. 2 technical, 1 lunch. The interviewers really want you to get in so they give you some hints. Prior to the interview they really set the hype by talking a ton of good things about the company.

The product interview was really straightforward, its just determining what metrics to look at to determine success, Youtube helped. Also, review A/B testing. Tech interview, I messed up on, I definitely didn't practice speaking out loud. The tables they give only describe 'int' 'string', which threw me off because I practiced with actual data points, so my brain froze. definitely practice that.
