Fairly long and detailed interview process. I didn't mind it though as it helped ensure they were hiring top tier talent that fit well with the company culture. I ended up doing at least 3 phone interviews, one with a culture ambassador, and 3 in-person interview sessions where I was interviewed by at minimum 2 people per session.

Pro: Recruiter was always quick to respond to emails and follow up with phone calls. Feedback process was quick between rounds. Process Cons: Multiple rounds of interviews. Phone, in person, in person again (this time, across the country), phone.

In the interview, you are asked dozens of seemingly meaningless questions. They are trying to get a feel for whether you have good reasoning and analytical skills. From their point of view, it is a very worthwhile interview. From your point of view, very little information about the job is disseminated, resulting in your not really knowing what you will do before you arrive.
