I was referred by a friend who works there which helped get my resume to the top of the stack. I had a phone interview first which seemed rather easy, making sure I actually know what I'm talking about and that I'm not crazy. 2nd interview they flew me out (not local). They flew me in the night before so I would be fresh. They reimbursed my expenses including a rental car. It was 4 hours of interviews with 7 people in 4 panels. Intense but friendly
