Vantaggi
To grow, to learn, to become a professional. P&G fosters an amasing openess and readiness to share knowledge among the employees, and that's probably the best thing about this company. I work in Product Supply, and I have to say that Product Supply is really adanced here; a lot of best practices are actually introduced by P&G on the market. Among the big scale companies (not IT) P&G has probably the best Product Supply, so that's a really best place to learn it. Also P&G is a grate place to train your communication skills, as in general people are very adequate here, and it's really hard to spoil your relations forever. As a result, you learn to work in a big collective, with dozens, or even hundreds of business contacts. Which is an outstanding experience.
Svantaggi
At least in Russia, the work/life balance is terrible. People overwork A LOT. They sit here from 9 am (sometimes from 8 am) till 8-9 pm, and some crazy people come into office even on weekends, or work from home. Both bosses and contractors do so; and all the mid-tier of workers as well (naturally). Anothing thing that isn't really ideal is the career growth speed. Theoretically, P&G is that big that you can always find a position you would like, however in practice it may need years to grow to the level you desire (even if you deserve it). A lot of people leave P&G for better work/life balance, but even more - just to jump over 1-2 levels, for a good position in another company.
