I guess it depends on the business unit ...
Pros
The firm is well regarded and colleagues who have been there for 20+ years cite a real opportunity for internal mobility. One woman has had 15 roles in slightly more years. (Although I wonder if that's just her or her experience at the firm.)
Cons
I work in Admin as a VP with 10 years' experience at other large banks. The senior leadership stresses "communication" and "mentorship" during town halls and the interview process, yet I see none from upper management in my business unit. They don't really seem to know who staff is, unless they've been there for ages - and while they all cite what a difference mentor relationships made in their careers, they aren't mentoring middle management in return. I don't know if I would've joined if I'd known how little career development, training, and guidance actually happens in this particular division. To be fair, I've heard different in others. Compensation is adequate, but they seem to be unwilling to make market rate or reward appropriately. (Our team lost a highly respected member after consistently great annual reviews and comp comparisons that he was being underpaid: the message was very much "take it or leave it".) And even though we are all doing "more with less", this year's bonus numbers reinforce that attitude.
