Epic Software Engineering interview questions

Talked to an Epic engineer at my University's career fair. Ended getting a response about two weeks later requesting that I do a online technical examination with ProctorU and also have a chat with an Epic engineer. Exam took roughly 2 hours & 45 Minutes. Questions varied from general math, to logic, to programming problems. Talk with the engineer was very friendly and non-technical. Mostly chatted about my resume, professional interests, and the work done at Epic. Programming problems were the hardest part but I ended up answering all (Some weren't the most efficient solution possible though). Got a response back asking to go to the Epic campus for an on-site interview. Before arriving they asked that I do a short online behavioral interview which took ~30 minutes. Hotel I stayed at was very nice. The on-site interview took several hours, mostly consisting of a tour of the large and stunning campus. Had lunch with other prospective hires and an Epic engineer. There was a technical and a behavioral interview as the last part of the day. I very much disliked having to do the ProctorU exam.
