Basically a corporate "Call Center" with monotonous and repeitive work, low pay, but at least it's a "well known" name.
Pros
The young co-workers. Great place to meet new people in the low to mid 20's. Almsot like a structured College Campus. However, management is much older but they stay to themselves. If you are young and not too concerned with salary starting out, but want a job with alot of cool people to hang out with, this fits the bill.
Cons
No advancement whatsoever. If you start at the entry level and are satisfied making $30K a year for the rest of your career with minor raises, then this is the job. No different than being a teller at a bank. You will make low 30's and have job security as long as you don't get bored with the phones, and trust me, you are on the phone ALL DAY! I suspect most people move on to other Financial Firms after a few years. The draw is the "Trowe" name and it appeals to the young people and they exploit it, but the work is pretty repetitive so someones gotta do it.
