Epic interview questions

I applied online on the Epic Systems website for the positions of Learning Coordinator and Word Artist. I was contacted 2 days later by HR and asked to take the Rembrandt assessment and a personality test. Several days later, HR contacted me again and invited me for an onsite interview. The following week, I went to the Epic campus for my interview. The day started at 9:00 am. with a tour of the campus (wow!), a software demo/presentation, and a one-on-one interview with a person from HR/recruiter. The interview lasted approximately 20 minutes and my resume and references were reviewed and discussed. I was asked why I left my last job and was asked to state "things that I am not." After the interview I was escorted to the test center and took a GRE type test on paper (easy) and programing exam on the computer (has nothing to do with the position I applied for). It took me a month to hear back from HR. I assumed that I wasn't going to be offered a position after waiting so long to hear back from them. Instead of offering me one of the positions that I applied or telling me that they are moving on with other candidates, Epic invited me back for an additional onsite interview (for a Trainer position). This time, I am to prepare a 20 minute presentation on any topic I choose. Technically, I am still in the interview process.

First round was a telephone interview, which is definitely not technical. They just ask about your experience and interest and few questions from your resume. Second was a programming assessment where you need to write program or algorithm for a given problem statement. It was total of 5 problems. Once cleared, then flew to Madison and had a one to one technical interview followed by a aptitude test and finally the HR interview.
