Pros
They are very good to bank with, employee or not. They have programs that allow you to cross train and advance. The hours are relatively flexible. If were less sales oriented, more focused on the customer. (That was before the merger, it might be less so now, but not necessarily).
Cons
Very political, if you hope to advance, you better be ready to play the game. There is definitely favoritism, and backbiting. Stay on everyone's good side, never speak negatively of anyone, because it will come back on you. They have less conventional hours, which can be a pro or con. They offer more flexibility, but you have a high chance of being required to work either Saturday, Sunday, or both; as well as evenings depending on your position. The pay can be somewhat less than other banks depending on your position.
