I know that Epic was hiring UX designers a few years ago. I didn't make it through their interview process, but I'm kind of glad I didn't due to the invasive nature of the remote test that I had to take.
They wanted my high school GPA and SAT scores to complete my application. I had my bachelor's, and 12 years of experience at the time. After moving to Madison, was glad I refused to give that info. They like their implementation teams right out of school, and work them to death
