Vantaggi
After just a few months of training, you very quickly get trusted with great responsibilities, which is a bit stressful at times but also highly rewarding. The work is meaningful and challenging, you get to own projects from start to finish, and you get to work on the full stack. You get to interact with sharp and friendly co-workers: developers, designers, QA. The environment is both professional (people are respectful and focused on work) and chill (no dress code, crazy art everywhere, friendly atmosphere). Even though it's a big company with many products, you can see the impact of your own work in the finished products. The campus is absolutely fantastic, everyone I've brought to visit has been completely blown away and for good reasons. The food is really truly awesome. The pay is great given the cost of living in Madison. And the benefits are very good too. The culture of "doing good" is sincere and being a privately owned company allows Epic to focus on the long term vision rather than the quick profits. The work-life balance is perfectly reasonable: I leave at 5:30pm everyday, in time to have dinner, play with, and put my kids to bed. People who complain about work-life balance in Glassdoor are typically not developers.
Svantaggi
The tech stack is non-standard (esoteric database, proprietary web framework, custom build tools) so many skills are not easily transferable, but the programming languages (C#, TypeScript) and other essential skills like project planing, architecture, design, code review, accessibility, etc. totally are.
