Pros
It's a job ! There are lots of different accounts and areas to work on if you can effect inter-company transfers.
Cons
You'll find many talented bright and enthusiatic people whose work has gone unrewarded, unappreciated and who have had the life sucked out of them. It's full of crony management who have all "sold their souls" for the price of their lucrative bonuses and packages. They are not interested in streamlining, in making processes better, or achieving efficiencies (which the real workers, the real talented people could bring in spades), and many have zero actual line management skills. Mostly they appear focussed and "bought into" some bigger picture that the workers are not party to. The end of year appraisal system is a devisive undefendable nonsense which the souless management have to carry out leaving real talented people starting to actually believe the unrealistic mediocre scoring they all receive to prevent promotions and pay rises. In short, it's one big game and the senior managerment play it for all it's worth keeping the status quo going to keep their lucrative positions, all the while at the expense of real, good, talented people whose efforts often go unrewarded. If you are prepared to sell your soul, play the game, tow the party line and not rock the boat, then I'm sure you will do well in which case roll up a trouser leg and arm sleeve and dive in.
