Pros
Procter and Gamble offers a great dynamic setting for newly graduate employees to grow, learn and develop. The company will provide you with a solid business knowledge, working framework and trainings. It offers good career opportunity until mid-senior positions, and possibilities to move abroad and travel (thou this might depend on the function you work in)
Cons
Procter and Gamble has a very set and standard way to conduct business, based on established and detailed processes. Roles can be very fragmented with limited and well defined responsabilities (as opposed to a more global approach). Once you have reached a mid-senior position room for advancement becomes scarce and the soft skills and appropriate P&G behavior becomes the key for success.
