Pros
Working at P&G will prepare you to work in other companies. By forcing you to commit to the whims of your manager, as opposed to the goals of the organization, you learn to pivot quickly. If you are one of the “anointed” there is nothing you can do wrong: you can steal other peoples work and barely do any of your own and you’ll still succeed.
Cons
If you are not one of the “anointed” there is little you can do right. This is not a company based on meritocracy (they tell you this explicitly over and over again in their endless diversity indoctrination). The only thing that matters are your immutable genetic characteristics. The person who rose fastest during my time at P&G was among the most incompetent and unethical people I’ve ever worked with; this person would steal other peoples ideas, lie about the people working with and for them, and wholly plagiarize work performed by their direct reports.
