Epic Software Developer interview questions

Received an e-mail from them asking to set up a phone interview. Accepted and spoke with a developer at Epic. He asked me a few questions about my background, my interest in software development, gave a quick technical interview and then allowed me to ask any questions about the company. I was then asked to take an online assessment with some testing company.

The whole process took about one month. Phone interview is quite easy, there are some onsite questions below: 1) Design a system to store patients' medical documents. 2) Talk about your summer internship and what's the most impressive bug you got in that internship.
