I gave BNYMellon a chance despite their terrible reputation and found to my annoyance that everything said about them was not only true but was much worse than I had ever experienced anywhere else (except maybe working minimum wage jobs in my 20's).
I thought depending on the department and manager I might miss the worse of their reputation (I didn't). I didn't even make it for 3 years until they laid me off despite being the top performer in my department (it was all dollar based on my salary. My manager fought to keep me and was shot down by his id--t boss). Within a few months the entire department quit, probably due to the way I was treated and their attempt to lie about why I was let go.
It will never get better working for them (I was out the door in 2017 and from the reviews here it has gotten even worse).
