Epic Internal Project Manager interview questions

I completed Epic's standard personality profile and was set up with a video interview a week later. Most of the interview was basic, verifying facts that I entered into the application system or that were on my resume. And then we got hung up on why I picked the graduate program I chose. My interviewer didn't seem to understand the general structure of graduate programs in my field and by the time I realized that we had spent ten minutes talking about it. That or it was some kind of weird test. I felt like that was probably what worked against me the most, and I honestly feel like it was a "luck of the draw" matter. Which is unfortunate because I really do have a lot to bring to their company and I would have liked to see it through further.
