Pros
Nielsen provides unparalleled data, information and products to clients. They are true innovators within the industries they serve. Senior management is bright and capable for the most part. The company is sensitive to work/life balance issues. Restructuring efforts have given the company a more focused approach but have also created difficulties.
Cons
The integration of businesses (and their respective corporate cultures) within the company has always been and continues to be a source of problems for both employees and clients. The clash between the cultures and processes of the media measurement and the marketing information businesses makes for a lethal cocktail for those employees caught in between. This has been exacerbated by the takeover of the company by private equity. Cost cutting and escalated integration initiatives have made matters worse. Uncertainty runs rampant and the resulting infighting, competition, and CYA mentality among employees has created a caustic environment.
