Pros
Epic has a strong culture and a very autonomous work environment. The company is a fun place to be and they make an effort to maintain that fun vibe. There is a lot of responsibility given to people early in their time there, although it may not show up in pay and advancement as quickly. Healthcare is a very complicated industry and if you enjoy a challenge, there are many challenges available to you at Epic.
Cons
Epic's culture will not be a fit for everyone. If it is not a fit for you, I wouldn't suggest trying to make it fit because you'll break before Epic will bend. Epic has a philosophy of never compromising or negotiating on things. While this can be good, it also means that they don't negotiate on salary, they don't change things to accomodate individuals very well. As a company, the Epic way is correct and it is not considered appropriate to question it, particularly when you are new. "Learn by doing" is a mantra, even if that is not a way you learn best.
