Pros
Lots of projects to work on, providing many opportunities for growth (if you can navigate the system). Few established processes in some business, so much room to make something new, in addition t the many process improvements always happening. Decent benefits, but salary and bonuses not keeping up with other offers. Good opportunity for travel due to global nature of the business.
Cons
Work expectations can be extreme, and unmanageable at time. Projects are ambiguous without clear process or decision makers, so everything moves so slow. Toxic culture permeates; poor treatment of women persists. Questionable hiring practices. Senior leaders often don't understand the business they have to run, and don't trust the teams doing the work for many years. More time spent writing strategy iterations than spent on executing strategy and doing the work. When projects fail, scapegoats are identified early and aggressively blamed.
