  • Epic Just Switched OA Question Banks, Old One Is UselessEpic Systems · Software Engineer · New Grad · Online Assessment · Jul 2026

    Epic's official guide has been updated — first a phone call with a colleague introducing the role, then an online technical assessment. It's completely different from the old question bank. I'm a new grad currently job hunting, sharing this in good faith. True/False/Cannot Determine — 5 min Each question gives 4-5 facts, and you judge 5 statements as true, false, or cannot be determined. Roughly…

  • Epic Software Engineer onsite: evolving patient-database design and backtrackingEpic Systems · Software Engineer · Onsite · May 2026

    I started the day with an online video overview that lasted about forty-five minutes. It covered what Epic does and the software it provides. After that, I moved into one-on-one conversations with engineers. One was a lighter discussion where I could ask questions and hear about their experiences. The next engineer conversation was more technical and felt like a system design prompt that kept bui…

The assessment was genuinely hard, longer and more challenging than I expected, and it was the part that required the most effort. After finishing it, I made it far enough to receive an offer. I ultimately declined because a better opportunity came…

  • Epic Software Engineer interview with HR call and coding assessmentEpic Systems · Software Engineer · HR Screen · Apr 2026

    My process started with a phone call with HR. It had a resume and behavioral focus, with some discussion of my background and questions about how I think and present myself. After that, I completed an assessment test. That was clearly the hardest part. It wasn't described as a single coding-only challenge, but the coding section pushed me the most. The test had to be completed before or after the…
