Applied online. After a couple weeks, I was invited to have a phone interview. The phone interview was very basic and relaxed. I was asked a few questions about why I was interested in the position, what I knew about Epic, etc., and I asked a few more detailed questions about the position. Within 24 hours of the phone interview, I also had to complete an online writing test and a personality test. Both were fairly easy. The writing test consisted of three short prompts and took a little over an hour. After a couple more weeks, I was invited to take a proctored online assessment. Basically, you take a series of tests with your webcam on while someone watches you. There was a math section similar to the SAT (word problems only though), a verbal section that seemed very similar to the LSAT, a programming section involving a madeup language, and a math speed test. A couple days after that, I was invited for an onsite interview. I was pretty impressed with this portion. Epic puts you in a nice hotel and pays for all of your food and travel. A word of advice: go to the (supposedly) optional dinner. The actual interview consists of a series of half hour meetings with various people from morning until mid-afternoon. It's fairly relaxed. Just think of plenty of questions to keep the conversation going when necessary. I also had another writing test at the end of the day. Received an offer about 2 weeks later.
