Epic Technical Solution Engineer interview questions

After application, I received a phone call screening to go over general eligibility questions. Shortly after, I was prompted to complete a behavioral/technical exam that was very easy and doesn't require coding knowledge to succeed. However, I had a negative experience during the final interview. It was 3.5 hours in total, although the first 3 hours were purely educational. During the last hour, you were tasked to complete a case study. My interviewer for this section was distracted, eating loud chips, and was generally dismissive of my questions. This hindered my ability to respond to the case study questions and damaged my perception of epic. Also, the pay is low considering how you're expected to work around 45 hrs a week.
