Applied online, received an email that same day scheduling a phone interview for a week later. A second phone interview was then scheduled a few days later, followed by a case-study which they gave you 24 hours to complete and finally a 5 person in-house interview. Overall, the interviews were not exceptionally difficult if you prepared and most of the people I spoke with were very friendly. They also spoke to me in Spanish during one of the interviews, I guess because they were considering me for the Latin American group.
