I applied through university. The process took 2 weeks. I interviewed at Epic (Chicago, IL) in Oct 2014
Interview
First it's phone screen, it's not hard, just a few questions and one or two simple data structure, the problem they ask me how to store the click events of five buttons. There are four parts in the OA, generally you should finish it in 4 hours, the last part has three algorithm questions, which is kind of tough.
Interview questions [1]
Question 1
there are five buttons on the website, and we want to record the click events of these five buttons, which data structure will be optimal and how to do it?
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.

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.
