Extremely long. First interview is 5-6 hours, the second is 3-4 hours. Be prepared. Bring water! Eat before you go! Dress in a suit. Extremely professional cube environment. Group interview and singles with each department. Very friendly people. Not sure they're happy with their jobs because everyone calls it "Micro-cheap" and talks about how they won't invest in any software to help people to their jobs better. Was a red flag for me. I'm not sure why people stay so long (which is what they want) when everyone I met found something negative about the company to tell candidates. It was quite a turn off. Also, if you haven't been at your current job for 5+ years, they won't really take you seriously as a candidate. They're pretty judgmental, so be ready to feel like every little thing you do and say is being scrutinized - because it is.
