Epic Software Engineer interview questions

One phone interview. This was a mix of technical questions along with HR questions. Technical questions were related to Threading, OOPs while HR questions were majorly around why Epic? What would u like to do in Epic etc etc.. After clearing that, I got a call for onsite. Onsite was followed by a written test of 4 hours (they don't give any time limits but earlier is better). Four technical questions, followed by Analytical questions, followed by MIS based questions. Interview was around 20-25 min presentation on your past work and experiences. Interviewer was impressed (atleast that's what appeared to me during interview) and he asked a lot of cross questions like What would you do if you were given more time to complete this project? Why would you do that?

Applied through career center. Then one phone interview, which is not technical at all. Then invited to interview on site. The compus is beautiful, but they are still using VB and some other OLD techniques...
