Epic Customer Service, Systems Integrator interview questions

I was contacted via email about the company. Applied for AV Technician and Customer Service. A couple of weeks later, I got an email regarding phone interview. The interview was about 20 minutes, with the recruiter telling me that I should apply for Windows System Integrator rather than AV Tech, and I did. Two weeks later, I received another email about an entry "exam" that I'm required to do, consisting of three parts - Math, English, and MUMPS. The MUMPS part is Programming 101. Several days after the test, I received another email regarding travel arrangement for an on-site interview at their campus. Flew there, met two employees whom took us (a group of six) out for dinner and a walking tour of Madison. I found out later from their employees that they flew in at least 20 people everyday, mostly college seniors with high GPA.
