I applied through college or university. The process took 2 weeks. I interviewed at Epic (Madison, WI) in Jan 2012
Interview
1st round: Epic HR e-mailed to schedule for a phone interview -which went really smoothly.
2nd round: Computerized test: The first half of the test was similar to the GRE quant questions, The second half was all programing, and I think I did horribly hence did not receive an offer.
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.
