Epic Software Developer interview questions

Applied online and got HR's email back on the second day. Then scheduled a phone interview, including questions about why epic, my background, and a question about machine learning(using SVM). Then did the online assessment. After that, got the onsite interview. Onsite interview starts on 8:15 (tooooo early). first is a demo about the software, then talk to one software engineer, get some ideas about the company. The third round is a case study, develop a data structure for emergency room. fourth round is a informal presentation about your project. Then go to lunch with one software engineer. After lunch is a campus tour and HR wrap up.

I get the phone interview and online assessment at same time. phone inter view is about 40 mins. We talked about my background, past projects and current project. I had been asked one design question in phone screening. The online assessment is not very hard, including 4 parts and took 3 hours to done. The coding part had 4 questions, including dp programming and string manipulating.
