Two preliminary phone calls. They then set up a 2 hour long Skype interview where you interview with 4 different team members for about 30 minutes each. They ask the typical interview questions along with one or two "outside the box" questions that are supposed to gauge your thought process on analyzing complex problems. Waited 2 weeks to hear back from the Skype interview. Finally got a brief email saying they were going to continue seating other candidates. It was a waste of time in terms of not getting the offer, but the challenging interview gave me some good interview experience moving forward. I just wish they hadn't left me waiting for 2 weeks... they probably knew they weren't going to hire me right after the Skype interview.
