1 technical assessment through their own system, mix of coding and logic questions. 1 3hr video interview: case study, behavioral, and orientation on their software. Ask good questions and you should be fine. No need to study.
I applied through a recruiter. The process took 4 weeks. I interviewed at Epic in Feb 2022
Interview
Got an email from a recruiter asking me to apply. I was then asked to complete some tests which took around 3 hrs. I then had a 30 minute phone call with a veteran TS. After which I was invited to do a zoom interview day which took around 3.5 hrs and I was also asked to do some additional tests which took around 1.5 hrs. The whole process has been very time consuming.
