I first had three phone interviews, consisting of "standard" technical questions that you can find elsewhere on this and other sites. About half of them were algorithmic questions, and the rest were design. For a couple of questions I had to write actual code, whether reading it to the interviewer or emailing them. I then had an in-person interview that was six or seven engineers from my prospective team, which was mostly more of the same, just harder. All of my interviewers were very easy to talk to and get along with. I knew very few of the answers just off the top of my head, but I talked my solutions out with the interviewers, including my assumptions and ways to make the problem easier.
