I applied through an employee referral. The process took 4+ months. I interviewed at Epic (Milwaukee, WI) in Jul 2015
Interview
First off , an introductory phone call from an Epic Software Developer whom provides basic debriefing of what the job entails. One week later, you will be asked to take an online proctored exam consisting of 4 programming questions in a language of your choice. If all goes well, then they will contact you for an onsite interview.
Interview questions [1]
Question 1
Count the number of character occurrences in a given String.
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.
