I applied through an employee referral. The process took 2 weeks. I interviewed at Epic in Jun 2016
Interview
I completed a skills assessment and phone interview, but did not have a second interview scheduled. The assessment and interview were separate from one another, and you can finish the assessment before doing the interview at all. The email I recieved about the assessment said you don't need to study for them, but if arithmetic or word problems are not your strong suit, it would definitely be helpful to brush up on those skills first!
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.
