I applied through university. The process took 6 weeks. I interviewed at Epic (Madison, WI) in Dec 2019
Interview
Pretty chill process. They fly you onsite and show you around the campus, have some demos where they show you the kind of stuff they do. The more technical sections come later. In one, they describe a real world type situation to you and you must describe - at a pretty high level - how you would go about creating a solution to that problem, using what algorithms/data structures. The other asks you to walk them through a larger scale app or project you have worked on, so come prepared with one in mind to talk about.
Interview questions [2]
Question 1
What would you use to implement a scheduling system for a clinic?
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.
