Pay: Base pay is near laughably low for corporate jobs and unfortunately the bonuses don't make up for them. They're based on a % of your net income (not pre tax) and tiered to higher percentages for upper management where I also suspect there is a bit of a wage gap compared to associate/middle manager levels which creates some naivety on to what employees actually take home.
Career: Opportunities for advancement and promotions are hit and miss but are ultimately not considered unless someone has to been a loyal WaFd'er for 8-10 years. Nothing wrong with it, just know it's a real old school traditional bank in how they view and value employee loyalty despite not necessarily returning it.
Siloed Departments: Departments within corporate don't really speak or even work all that much together.
