I applied through university. The process took 3 days. I interviewed at Epic (Madison, WI) in Mar 2010
Interview
Pretty much like the others have said.
First, a phone interview, basically a preliminary vetting.
Then I was invited onsite to take a skills assessment. You're graded on both time and accuracy. It's basically a baby LSAT, so if you took that, you're in good shape.
Finally, there was a day-long interview where they also introduce you to the Epic campus and product. This is where you do a case study and make a presentation, and go through a series of 1:1 interviews.
Not invested in who they're hiring if they rely heavily on multiple assessments for applicants to take (personality quiz, etc). These are unpaid and take hours. A poor use of time.
Intro zoom call, and several hours of tests on a lockdown browser before even getting to have the first ten minute phone interview. Phone interview was basically combing through my resume and any gaps.
After submitting the application, there was a personality assessment and a technical assessment to test your thinking skills. The technical assessment had 4 parts, some of which took a long time(~1.5 hours) while others were quick.
