Pros
Overall while working there they treat you nice, Opportunity to work with modern stack. Strong on Diversity & Inclusion - they make sure to have diversity from all backgrounds. Strict on Agile in some teams (you need to pick up the right team..) you get free subscription to Udemy to learn new technologies
Cons
The second they not need you they'll throw you under the bus. I worked 3.5 years as a Principal UI Developer Senior Vice President. In my contract I had to give 30 days notice if I'd choose to leave. One day my manager calls me in the middle of the day and say it's my last day, in few minutes I need to log out. No notice. Forget about getting your vacation days. Starting in few minutes you don't have salary. This is not how you treat your employees. Even when I was a contractor for BNY Mellon before switch to Full time I got from the contractor two weeks notice. bottom line: wouldn't recommend work in BNY Mellon.
