I applied through university. The process took 2 weeks. I interviewed at Epic (Verona, WI) in Nov 2014
Interview
I talked to them at a college career fair and decided to apply to their company. First there was a basic phone interview where they ask you about your background and your interests, and you can ask them about their company and the job you are applying for. A couple of days later they had me take a proctored online skills test, which consisted of math/logic, puzzles, a section where they teach you a language and then ask you questions about it, and 4 programming exercises. It was fairly challenging and took a couple hours to get through. Then there was the onsite interview where they give you a tour of the campus, and had a couple of interviews. These interviews included a peer programming exercise with one of their employees, a discussion of your past projects and experiences with programming, and a behavioral interview where they ask you your strengths and weeknesses and what others would say your strengths and weaknesses are. In the end I didn't end up with an offer, but it was still a good experience.
Interview questions [1]
Question 1
If 3 lumberjacks can cut down 3 trees in 3 days, how many trees can 12 lumberjacks cut down in 12 days?
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.
