Pros
Amazing benefits and bonus! I'd equate Retirement benefits as 99th percentile, Health Insurance as 85th percentile and PTO as 75th percentile. They also offer a generous stock purchase plan match, tuition reimbursement, gym membership reimbursement, Free short term & long term disability insurance and a company paid life insurance policy equal to 3 times your salary! Annual merit increase and bonus that are almost always paid at 100%. The people are great and many cutting edge changes are taking place on a daily basis. Company culture is the most collaborative that i've seen and work/life balance is an actual thing there. They are investing heavily in technology and marketing and should see incredible results from this moving forward.
Cons
I've worked for several other firms and can't think of a single thing that isn't better at T. Rowe.
