The interview was smooth. The phone interview screen appears to evaluate how much you know about the company work environment (which is apparently very cult like, an inside joke is "don't drink the Kool-Aid") and pay expectations. They want to make sure you are going to be hard working, willing to travel often, and not be frightened of their unheard of MUMPS/Cache database. The skills assessment involves about 5 short programming quizzes which takes 1-2 hours.
