Work satisfaction and contentment are completely dependent on the team you're on, and the people you know.
Pros
Notoriety and reputation brings some of the best talent onboard. In my 20+ year career (5 at AIG), I've learned that you can teach an old dog new tricks - as long as you're on the right team.
Cons
Old school mentality within senior leadership. Not flexible with work from home, although they tout this as one of their main perks. Haven't had a raise since I started even with solid performance reviews every year, but the cost of living and commuting to Wall Street has increased. Won't pay for my certification upkeep or any new certification even when directly related to my job - states no budget but leadership still seems to have enough money to host offsite sessions around the world. And bonuses? Lets just say that favorites or people who are connected seem to get the biggest piece of the pie.
