Epic Technical Problem-Solver interview questions

I had a very basic phone interview--it was about a half an hour. I prepped for it, but there was no need. They didn't ask any "interview" questions, only basic questions like why do you want to work for EpIc--that sort of thing. It was super relaxed. I interviewed with an employee in the role that I am applying for. I'm still waiting for on-site interview, which I have scheduled in a few weeks.
