I applied online. The process took 2 months. I interviewed at Epic (Madison, WI) in Oct 2014
Interview
Brief phone interview to ask a few questions about your resume, followed by a long at home coding test. Someone (a third party) watches you complete a test which involves a coding and math test. The math portion tests quick calculations of common things none of which are above algebra. The coding questions took me a while, but were nothing super tricky or unheard of. After the test, I heard back fairly quickly for an onsite interview. The most important parts were a technical project discussion interview and a behavior (tell me about yourself, what you want to do) interview.
Interview questions [1]
Question 1
Given an NxN board write code to determine if there is a winner, given that they are playing a game of NxN tic-tac-toe.
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.
