Epic Technical Services Problem-Solver interview questions

Referred by a current employee to apply for the position. Received an email from HR within 24 hours of my submitted application looking to schedule a brief phone interview. Confirmed availability and had a 30 minute phone interview with a current employee in the Technical Services field. Interviewer asked questions regarding my education and professional experience as well as some standard interview questions (Why do you want to work for Epic? Where do you see yourself in 5 years?). Overall, very easy-going conversation and seemed more like a phone screening than anything. I was told to expect information from the original HR contact about completing upcoming assessment and personality tests. Received email within two days of the phone interview about when and how to take tests. The interviewer explained that once the tests are complete, the final step in the interview process (if they decide to move me forward) will be an all day, on-site interview on the company's campus. Currently, the tests have been scheduled but have not yet been completed.
