Pros
Nielsen is the leader in market research and intelligence so there is company name recognition, a solid client base and tons of valuable raw data. The company provides an excellent opportunity to learn about individual categories and industries because it often provides the data that is used to evaluate players within that category or industry.
Cons
Current morale is bad. Recent restructuring has made product development a tortured process. This results in missed deadlines and botched operations for processes that previously had no issues. There is a lot of confusion about what people's roles are. New job classifications like 'product leadership' have been rolled out without any clear explanation of what that actually means. IT and operations have been grouped into Global Business Systems. Generally, people have not bought into the re-org which is not surprising because it has never fully been explained.
