Pros
Absolutley nothing. Which is a tragedy, because Nielsen was once an absolutely great place to work. I wanted to retire here. The culture used to be great, and I really loved being a part of this place. I loved my team, my management, and the people.
Then along came the current CEO who is the classic example of a person who knows the cost of everything, but the value of nothing. He took over and ran the company full speed ahead in to the iceberg. And to try and save the sinking ship, he laid off literally thousands of highly experienced, highly trained, and highly engaged people to replace them with fresh overseas hires who know nothing about the company and expect them to be trained from the ground up to replace literally centuries of collective expererience and client relations. It's a disaster. This CEO shouldn't be trusted to run a lemonade stand.
Cons
Everything. Pay, job security, culture, management. Nothing is good here anymore.
Don't take a job here unless you are truly desperate. And even then, it should only be as a stop-gap until you can find something else.
