Pros
The real story here is culture - investments can be full of big egos inflated further by their bonuses, but T. Rowe Price really treats investing as a profession. "T. Rowe Nice" is a real thing, and can make working hours enjoyable. There's a real open-door policy and lots of thoughtful and lively debate throughout the company.
Cons
Technology is something all companies are grappling with, and the firm has a lot of work to do here -- it can be frustrating navigating archaic systems or trying to find internal data. Workers need to be 'entrepreneurial' to do thing systems can't handle. Downside of a collaborative culture is very slow decision-making. Relationship-building is often important to progression, and can make advancement seem political.
