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.
Interview questions [1]
Question 1
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.
Medium level leetcode and then a very basic system design question as a final round interview. Overall, smooth and simple process. Only one technical and it was the first one.
Interview questions [1]
Question 1
How would you design a system to minimize wait time at a health care center?
First round is a thirty minute phone call with one of their developers. The other part of the first round is a three hour exam with IQ test style logic questions and coding questions.
[OA] OA was fair. Programming part are leetcode easy and easy-mediums, straightforward simulation, backtracking, dfs, strings, etc. No DP/graphs but ymmv.
[Final interview] (Case Study) I think the interviewer came up with their own prompt. It's mostly discussion-based, with a virtual white board. It's not too technical. I'm guessing its testing your communication/logical reasoning than system design skills. (Pair programming) 1 question, same format as the OA on the same platform, leetcode easy.
[Overall] Technical difficulty isn't bad. Interviewers who are current software devs seemed friendly. Had a good experience, yet got rejected.
