Cons
There are many downsides to working for the Bank of New York Mellon (BNYM). I worked in the Master Trust department, which perfromed accounting for pension funds and other large institutions. The work was extremly boring and unsatisfying. I would only have to really "work" 2 weeks out of the month. This may fine with some people, but not being challenged or growing professionaly is a problem with me. The company treated their employees like garbage, had poor morale, and provided non career advancement. I am not some disgruntled former employee. I was always given excellent reviews, given high % raises, and put on a "special" program where I recieved a raise every six months. This program was "special" because you weren't allowed to tell anyone you were on it. If you had a program like this and wanted to provide an incentive to your employees to work harder, wouldn't you want to tell all the employees about the program? Stay away, don't even consider it. Even if this is your first job offer out of college don't accept it. It wil only set your career back in the long run.
