Pros
It's a great company! Their ethical behavior and principles match my own. They are flexible and your career is yours to manage. P&G has a system for everything. These systems include: work and development planning, training, promotions, travel, expense reports. There are acronyms for everything and it will take a while to get to know them. P&G values people who transfer into new roles and bring their experiences from other roles. They continually are looking to develop the next generation of leaders.
Cons
It's a big company - you can get lost in the shuffle. Their compensation is not competitive in high cost areas as they pay on a national average. P&G has a system for everything. If structure is a bother to you this is probably not the place you want to work.
