There's an initial call, then some online testing, then they have you come in. If you live far away (a lot of people who work at Epic seem to come from surprisingly far away), they'll pay for your travel and stay to come in.

When you come in, it seems like they're more trying to sell themselves to you than having you sell yourself to them. Most of the questions directed at you seem to be just to get to know you more so than seeing if you know what you need to know.

They'll have you talk with someone in your field, show some demos of their software, give you a tour, and give you lunch at their biggest cafeteria for free.

Lastly, they'll hand you off to HR to answer the rest of your questions before letting you go.

As far as I can tell, if they've brought you in, they're planning on hiring you.

In the testing, they teach you this made-up language that has really weird properties to it and ask you questions to test your understanding of it. It was surprisingly difficult.
