Great career advancement opportunities Work from home opportunities Travel to other offices to collaborate After work events to get to know management on a personal level Peers are great and many have become friends outside of work

Cons

Everything is required yesterday Initiative Improvement is a big focus to the point that any improvements made are not good enough (i.e., what else can be done to make it better) Little recognition for the work that has been done When high management asks you questions, feels like there is a reason they are asking rather than being generally curious
