Pros
Looks good on the resume. Interesting projects going on company-wide.
Cons
Top-heavy organization. NMR is a monopoly when it comes to TV ratings, so senior-level managers are not motivated by the market to innovate, progress, etc. The big earners at Nielsen sit and collect paychecks, and they do it for 15, 25 years plus. The likelihood that they will get canned is almost null, so upward mobility for younger staffers is basically impossible. The pace for professional advancement is far too slow. Because of the monopoly and the "unique market position," the senior-level people do not have very applicable real-world experience. They are only able to function (on auto-pilot) at Nielsen, because that is the only company they know and understand. Elsewhere in the real business world, they would be lost. This all translates into archaic skill sets and poor people management. This place was the epitome of office drone and red tape.
