Took me into their office. Lasted about 2 hours. Got to meet 4 of the employees and also got a tour of the office. We went out for coffee during the first hour and they asked me general questions about myself. The second hour was more formal where I was interviewed by 2 different engineers.

The interview process for me has been consistent, starting with open interviews, interview with regional recruiter, and interview with office you're applying for. In my most recent job application, I attended open interviews, and in the follow up 2 weeks later dismissed me as a candidate for no indicated reason.
