You have a phone interview, then a skills assessment, and onsite interview. The phone interview is mostly behavioral, and generally straightforward. You talk with an actual software developer about Epic.
Then the skills assessment consists of a few tricky math and logic questions, where they want to see how many you get in just 2 minutes, and four programming questions. The programming questions were quite tricky, and you do need to write actual code. You get no compiler and/or test cases to tell you whether or not your code works. You get unlimited time for the programming questions, but they do consider speed in their evaluation.
I did not get an onsite interview invitation, and was very annoyed. I previously took this same type of assessment when applying for TS a few years ago, really had difficulty solving the questions then, but got an offer. After declining the offer at that time, I have since improved my programming skills, and felt much more confident about the assessment this time, only to get a rejection.
