Pros
Epic has made an effort to hire some of the best and brightest young minds out there. Your coworkers will be absolutely amazing. The on-site culinary team is absolutely top-notch. Your work has a noticeable impact on your own life, and those of your friends, family, and community. The benefits package, especially the insurance, is amazing in almost every respect. You have real ownership of your work right from the get-go - the sky's the limit, and you're in charge.
Cons
You have real ownership of your work right from the get-go - if you let things go south, it's all coming down on you. New employees earn only 10 days of vacation per year. You also earn 6 days of sick leave, but even the 16 days of PTO/year total is pretty low compared to what's out there. Team leaders tend to put in 50-60 hours a week because they're that passionate. If you don't make it clear that you're not up for that, they'll expect the same of you.
