Pros
T. Rowe Price is one of the friendliest companies I've worked for. The company really seems to care about its employees and gives great benefits. The tuition reimbursement is great - unlike other companies, there's no limit to the amount of money you can be reimbursed. There are many chances for advancement, as well. T. Rowe actually encourages employees to switch positions every so often, and even has an internal website with job postings. Also, they often allow alternative work schedules and allow employees to work from home occasionally.
Cons
I am in an entry level position, but interned with T. Rowe Price and several other companies before. T. Rowe Price didn't seem to take this into consideration when they gave me my offer, which was on the low side.
