I applied through a recruiter. The process took 2 weeks. I interviewed at Epic (Atlanta, GA) in Mar 2015
Interview
There is a phone interview first up, then an online proctored exam and if you clear that, then an onsite interview. The online exam consists of general IQ questions, basic math questions, a section on a custom programming language whose basics are explained to you and then you have to answer questions based on that. The last section consists of 4 programming questions. You can code in either C++ or Java.

Question 1
The phone interview was a general one, asking me what I am interested in, any questions I had about the company.
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.
