I applied online. The process took 4 weeks. I interviewed at Epic (Madison, WI) in Nov 2015
Interview
There are three parts to their process. First comes the phone interview with an employee in the department you're applying to. Then, they give you a net proctored technical examination. If you pass that, you are invited on site to do a tour and final interview.
Interview questions [1]
Question 1
Phone: No technical questions. Standard sets like "Why Epic?" and "Explain this experience in detail."
Technical: General intelligence multiple choices and then coding challenges found on code sites like Topcoder.
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.
