Pros
Working for an industry leader which provides employees with great exposure. The firm offers great hands on experience with detailed review process. It offers the employees quick rotations in various elements of the value chain allowing you to better understand how business works as an integral unit which is bigger than the sum of its part. Current CEO (AG) is a great business leader with interesting insights to innovation management. The company now breathes innovation in a way very few fortune 500 do. Credentials are great in business school or industry helping land great jobs down the road. Bottom line: great learning opportunity and brand
Kontras
Too structured at times and learning curve at times is not as steep as you would expect. 4 to 5 years is a good period to stay and learn but not become too rigid as some middle managers tend to be. Its an old boy clubs (especially the UK branch) hence promotion is very dependent on being liked by the right people. Luck is an important factor in getting promoted: if you have engaged with the right people at early stages (because your role lent itself to that) you will get promoted fast, otherwise it is very slow (regardless of your skill - it feels like you can just get lost in a job)
