It was a very sraight forward and standard 30 minutes interview with 3 rounds. You'll be contacted by a recruiter or HR representative if they are interested in you. Their HR partner will decide whether or not you make it through to the next round. Seemed standard and informal. They make you feel comfortable.

Very quick - I interviewed with recruiter, HR rep, and executive. I received a job offer before I reached the elevator on my out of the building. I spoke with a recruiter, met with her for coffee and then she scheduled a meeting with their HR rep and the hiring executive.
