Interview started with a quick recruiter call to discuss my background, experience, and interest in Epic. Answered any questions I had about the position and work at the company. Next round was a proctored online technical exam, expect at least 3-4 hours in length. Consisted of 3 rounds, one extremely quick round of logic / math questions. Next round was answering questions about a fictional programming language, then finally a few programming questions without the aid of a compiler. Proctor was a bit difficult and would harass me about looking off to the side (was just thinking). Final round was a presentation about Epic's software with several other interviewees, a group QA session, an easy system design round, then a final discussion with a recruiter. Have good questions prepared and be social, the onsite is mostly a personality test. After I received the offer I was given the option to tour Epic's campus, which I did. It's a nice location but gave off the impression of being a stressed-out corporate Disneyland. Recruiter was extremely helpful and transparent, guided me throughout the entire process. Patient and gave me plenty of time to make a decision on the offer.
