Everyone else has touched upon the process to a fairly lengthy degree, and I don't have much to add. You start out with a phone interview, are asked some very general questions, and then sent a follow-up test that you have to take in front of a webcam proctor. They then fly you out onsite to see their facilities, which are fantastic.

Expect multiple rounds of interviews involving typical interviews with recruiters, as well as taking a logic and coding test (even if you won’t be coding, you’ll still do some basic stuff on the test for it), and will also need to do a persuasive or informative presentation.
