The interview process was not too bad. I applied over a year ago and had passed the assessment and phone interview and was offered an in person interview but had to turn it down for another opportunity. When I reapplied they called me within 3 days and offered to fly me in and interview immediately. The interview was long but very professional compared to many companies (although there is a casual dress code). Overall not high pressure and I thought it measured a potential employees abilities quite well.
