Epic UX Researcher interview questions

For the interview with Epic I had 2 exams, one of which was a personality fit, the other was a 4+ HOUR PROCTORED exam (similar to an SAT). The exam featured everything from engineering questions, math, science, reading, and logic. This was UNPAID and at one point, the proctor could not get their system to work, so I had to reschedule for a second 4-5 hour block of time. I would not recommend. When I asked why I was taking this as it was unrelated to the role, I was told that "Everyone takes the exam." Which I suppose could mean everyone from the CEO to the custodial staff?
