I applied through a recruiter. The process took 5 weeks. I interviewed at Epic (Madison, WI) in Feb 2010
Interview
First, you will have a phone interview with one of their engineers. In my case, the person interviewing me just worked one year for the company and it seemed that she was doing something on the side while interviewing me on the phone. It was really dragging, to the point that I tried to help her to get through the interview. After that there will be a skills assessment with a local proctor. Each phase is 2 weeks apart. So it will take a while. Final stage will be an invitation to Wisconsin, but I didn't make that stage.
Lots of testing, pretty automated process. I felt like it was hard to get real feedback from them afterwards. All in all, pretty standard. Make sure you do some prep for the testing section
Epic has a very thorough and comprehensive interview process. From an initial screen to a series of tests to gain understanding into your logical problem solving skills. One amazing aspect of the process is they will fly you up to Madison, WI for further interviewing but also a chance to see the city and their campus, both of which are breathtaking.
Initial phone interview and online assessment.
Followed up with an Onsite interview a few weeks later with multiple teams and coding interview. Received offer within a few weeks after the on site interview
