Pros

Cons
Be prepared to for senior management to want cutting edge technology without approving budget to implement that technology. There is tremendous ambiguity within corporate which makes achieving your objectives extremely difficult. The strategy of growing via merger and acquisition means everything changes from day-to-day. Training and professional development is non-existent at the corporate level. The corporate experience is a frustrating one if this sort of environment is not your style.
