I applied through college or university. The process took 1 day. I interviewed at Epic (Madison, WI) in Nov 2014
Interview
I got the onsite request 1 week after I finished the online assignment. The process is simple, no technical question. First they give a short instruction on their company and products, then we have a chance to ask an engineer kinds of questions. Next there were two 1 to 1 talk. They'll let you talk about the things on your resume. After that another person came in and asked me a question, non-technical. This is what I did in the morning. After lunch they gave us a tour of the campus, it quite interesting. At last there were a talking to a HR.
Interview questions [1]
Question 1
Image a situation that a patient make a call to the hospital, the person who answer the call should allocate a doctor to the patient. If this guy leaves for some reason, how could the doctor find the patient?
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.
