I applied online. The process took 4 weeks. I interviewed at Epic in Apr 2009
Interview
The interview process was straight forward and well executed. After a short phone interview and personality test, I took some written assessments. After those were scored, I was invited on site to an interview, which lasted an entire day. They tell you everything you need to know so just pay attention and plan accordingly. Even if I didn't get an offer, I would still have considered the interview a positive experience because you get better at interviewing every time you do one.
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.
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.
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.
