Pros
The on the job training at Nielsen was very benefical to associated when it was available. "Nielsen University" offered both Computer Based Training as well as Classroom training which helped with associate development. In addition to the training and development the the associates at Nielsen are real people and were always very nice. Everyone shared common goals so it made for a fun place to work. Most offices had outings or functions that would get associates all together under 1 roof so you got to know the other side of someone who sat across from you or across the office from you. Lastly, the name "ACNielsen" goes a long way everyone knows about or as heard of the Nielsen ratings.
Cons
The downside of working at ACNielsen or at any corporation for that matter was the annual raises. Typically the raises averaged between 2-4% and sometimes were based on how company faired for that given year. I don't know what the range is today but when I was there 2 years ago that was what an employee had to look forward too after working hard all year long. If you were lucky enough to be bonus eligible you were entitled to your bonus after you worked for the full year - however you didn't receive your bonus check until March of the following year!!!!!!
