Pros
Very good work/life balance, several recent innovation initiative that are real breakthrough for the market (Big data / hana, mobile, Saas) which bring as many really interesting professional opportunities. Global company where product management can have a global reach on business. Strong intercultural background, product management is often involved with many sites & cultures as well with different technologies. Pays well.
Cons
Many hierarchical levels, which brings executives too far from the reality and often inaccessible or unconcerned, with lots of politics, all this is bringing tons of inertia. Cumbersome organisation intended at fitting everybody, groups are sometimes redundant or useless. HR totally inefficient to enable mobility or support careers, while such a large company actually offers so many opportunites internally.
