Pros
There is a fair expectation of security. There are no layoffs. Benefits package is comparable to their competitors.
Cons
Compensation is 10 to 25k less than their competitors. It is fairly clear that they consider you replaceable. The centralized HR has no idea who is a good employee and who is not so raises are not assigned accordingly. Extra effort will get you nowhere because of this and you should expect 3% yearly no matter how well you perform or how hard you work. Policies on dress code and employee appearance are out of date. If an underwriting assistant job is offered to you I would not recommend taking it. Advancement from that position is extremely limited and the position is the catch all for the things that no one wants to do.
