I applied through college or university. The process took 2 weeks. I interviewed at Epic (Verona, WI) in Mar 2011
Interview
Dropped Resume at a career fair and got a call about 2 weeks later from a project manager about the Job. Really informal and a week later got an e-mail about a fly out. Epic want to be secretive about their interview process to ease everyone's tension, and in my opinion it works. Other reviews on this site detail the process well. Every single person I met was really nice and made you feel right at home. In addition their campus is beautiful and casual dress code was a plus. Got offered a week later and accepted. Seems like a lot of work, but rewarding.
I applied through college or university. The process took 1 day. I interviewed at Epic in Nov 2010
Interview
The interviewer was very nice and was easy to talk to. He asked me basic interview questions such as Why Epic? Give me an example of a difficult decision and how did you handle it? etc.
