Very thorough, a lot of vetting, lots of behavioral questions, so be prepared for "Tell me about a time when this happened, what happened, what did you do about it, how did you solve it, what was the end results" those types of questions. Usually you do a phone screening with recruiter, then phone screening with hiring manager, then final interview is coming into the office for 2-3 hours meeting with 3-4 different people back to back. Usually two people from the team and two managers.
