Epic Software Engineer interview questions

Epic's interview included a written test, a personality test, and an in-person interview. They have a well-organized interview process, and I was one of many candidates who interviewed that day. The interview took place on their beautiful campus in Verona, WI and included free lunch at their in-house cafeteria. For the most part, the interview was smooth and easy. After the interview, I was asked to give a reference from my current employer, even though I hadn't announced my departure. I was very surprised and uncomfortable with that, but eventually they compromised and let me use a reference from a previous job.
