I applied through an employee referral. The process took 2 weeks. I interviewed at Epic in Oct 2021
Interview
The test was long and fairly confusing but not really anything you could study for, more testing critical thinking than crystalized knowledge(except the coding part, it would help if you have taken discrete math/ logic or computer science with the leetcode section) but overall the other parts of the interview were very straightforward, fairly behavioral with the 'case study' was mostly a discussion and not intimidating at all.
Interview questions [1]
Question 1
standard behavioral type questions, nothing too crazy.
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.
