I submitted my application online and got contacted by an Epic recruiter pretty soon afterwards. We scheduled an initial phone interview, in which the interviewer simply went over my resume and confirmed whatever was written in it. It was a zero-stress thing.

A week or so after that, we scheduled an on-site interview. It honestly didn't feel like an interview. I basically talked to a bunch of Epic employees. They told me about Epic and Madison. I asked questions back. There was a brief campus tour and lunch at Epic's cafeteria with an employee as well. The official 'interview' was essentially a casual conversation with an Epic employee. They seem to be looking more at your aptitude and ability to learn new things than what you already know. Just be calm and be yourself.

I had to take a programming test at the end of my interview, as well as some very basic math/etc. tests.

I was a bit unprepared for the tests at the end of the interview, since I wasn't expecting them at all. But nothing was truly difficult.
