Got contacted after meeting with a rep at a career fair. First wrote a software test which remains the same as described by the the other reviewers. Then, got called into an ~2hr interview where I met with HR, R&D director, and group leader in sequence (1-on-1).

Most of the interview process took place at their office where I did a 3 hour test and then (after that was deemed acceptable) a one on one interview with the person I would be working with, which lasted about an hour. Then I met with the product manager and saw the server room--which was pretty neat. Then within a couple days I recieved a phone call from the hiring manager who talked to me about my expectations and other offers, then they made me an offer. Since the offer was made I was taken out to the office again to meet some people who had come to the company more recently. Those talks were very helpful--push for that if you have the chance.
