Pros
Financially strong, lots of opportunities, sophisticated environment, international, fundamentally sound in its attitude to people overall, pretty talented people and genuine concern for employee safety.
Cons
Big bureaucracy, slow, dull, opportunity for creativity and initiative very limited. Senior management pretend to care about people but care a lot more about politics - probabyl no worse than other big corporates though. Senior management are bright and mostly competent, middle management not much better or worse than other large corporates. Politics an dplayign the game matters a lot, and individualism is not generally welcomed. Pay is good and most of the employees do not understand how well off they are (in that respect) relative to the real world. A lot of cynicism among employees who feel pretty remote from the decision-makers.
