It really depends on who you want to be. AT experience from the beginning would be a great plus on your professionalism and maturity of thinking style; on the other hand, if you really enjoy the process of going into marketing campaign details and see your idea have a big impact on the market, you probably would find P&G MKT very interesting.
P&G marketing is the best place for gratuates to learn how to do marketing and build brand. if you just want to be Consultant, don't recommend you joining in P&G. but if you are interesting in marketing, P&G is the best. if you can be promoted as brand manager to lead one single brand covering advertising, public relation, launch event, roadshow, channel within 3 years, you can be named as master of marketing. but it is not easy.
