Three parts: phone interview, assessment, final all day interview. Phone interview was expected questions like why Epic, where do you see yourself in 5 years, etc. Assessment was basic coding logic stuff and some other standardized testing stuff. Final interview was a demo, questions to person in your position, case study, and HR interview. Received an offer maybe 3 weeks after my final interview and had 20 days to make a decision. It was a very positive experience!
