The process took 3 weeks. I interviewed at Epic (Verona, WI) in Apr 2012
Interview
Initially I was contacted by email to take a brief online quiz. After that, I was again contacted for a phone interview, in which I was lobbed a number of relatively easy questions. At this point, I had to go to a local testing center to take a combination of a mathematics and programming exam. It should be noted that the programming language was their invention, so that one wasn't expected to come in with solid knowledge of any existing programming language. After waiting for a couple of weeks, I was contacted again and flown out to Verona to undergo the interview process there.
While there, I went through a brief writing test, an interview with someone in my field, an interview with someone in HR as well as numerous information sessions from individuals in the field I was applying for.
Phone interview with someone in the role followed by aptitude based exam. After scoring sufficiently on aptitude exam, more recruiter interviews and on-site visit.
The recruiter/phone interviews were fairly standard and aptitude exam is something you have to just go in blind to
