Pros
Benefits are pretty outstanding (one of the best I've seen) and they advertise their "total" compensation package as being very generous. This is true when you consider that they multiply your salary by 15% and drop that into a pension account for you and let it grow in their mutual funds. People are pretty nice for the most part and offices are updated. Upper management is easy to talk to and usually willing to listen. Opportunity for advancement is there and definitely supported by upper management.
Cons
Things take very long to take place. Since it's a financial institution, projects and such move at a slower pace... to ensure that security is not breached and that no application breaks. Don't expect things to happen overnight. And don't expect to advance as quickly as you'd like although the opportunities are there.
