I was contacted via phone by a current employee who asked questions about my background, expertise, interest, etc. Most of the time was dedicated to her telling me about life at Epic and the requirements and expectations of the job. The whole experience was not too stressful, as the interviewer had a friendly demeanor and was open to answering any questions I had about the company.
I applied online. I interviewed at Epic (Madison, WI) in Mar 2017
Interview
The phone interview was very easy and only 20-30 minutes. There was a logic/math/personality testing section you had to complete over ProctorU and it was not overly difficult, but someone told me that it knocks out about 70% of applicants. After, they flew me to Madison for an on-campus interview. It was 8:30 am - 2 pm and consisted of a few interviews, a presentation, a case, and a tour of the campus. Very beautiful campus and it was fun to engage with current employees.
I applied through an employee referral. I interviewed at Epic (Madison, WI) in Apr 2017
Interview
Phone interview is super easy just to get to know about the company. No tough questions at all. 2 online tests they send you afterwards. One looks at personality and basic problem-solving questions. The other is a watered down GRE with some coding at the end. Nothing super challenging but very important. If they like you they'll invite you up to Madison for an in-person interview. Immersive total day interview that introduces you to the technology, company, and culture. Two interviews, a group scenario, and mini-tour.
