Pros
You'll learn what you definitely don't want from an employer. I enjoyed the exit interview.
Cons
Micro Management (Or is this exposure to Management...) Toxic Management - Phone would ring at all hours and expected to answer. Organisation is a revolving door of individuals, if you don't "do and give both kidneys" you are removed quickly. I had heard rumours of the behaviour and working ethics, but it was far worse than I anticipated. Hyper Aggressive organisation where the company is unwilling to engage with clients. Damaging your own personal relationships with clients and you end up questioning your own morality. A few "managers" who claim to be VPs in their own head, have accelerated through the company and have no management training.
