Pros
Large company, good benefits. Some lower level managers and regular people who work there are stellar. They are very committed to doing their level best despite being told there will be no merit increases, no bonuses, increased workloads, and in the face of some real egg-on-the-face moments of the past few years.
Cons
Weak upper management. Group-think in the extreme. Promotions tend to occur if you fit into extremely narrow demographic: Between ages of 25-35, Male, and White. Diversity is a value spoken about, but not practiced well. Money spent on business seems to be extremely lop-sided... spent on perks at upper levels, but not on providing mid-managers and first-line managers with the tools to actually accomplish job. Since melt-down, we have internal groups charging other groups for use of products already owned (and operated by Citi)... showing income. That's like me charging myself for cleaning the kitchen, then reporting that as a business expense on my income tax report. It may be legal... but it hamstrings the efficacy of the rest of the organization. So, we stopped using those Citi resources that charge.
