Vantaggi
The opportunities young people get at Epic are unmatched. I grew up around NYC and most of my college friends worked in finance after graduating. Four years later I'm confident that I was given significantly more responsibility at Epic than my friends, many of whom worked as illustrious financial institutions. Epic has a "sink or swim" mentality, but that's great because they actually let you in the pool. Epic's values are fundamentally sound. They are a responsible employer and do care about the wellbeing of their employees. Epic's extreme commitment to their customers is admirable.
Svantaggi
Some management actions at Epic seem naive. Epic's compensation for employees working internationally is not market-competitive. Epic's development process is (intentionally) slow. Expect to work at least 60 hour weeks during your first year (I don't find this necessarily a con, but others might).
