Pros
Offered the job after just one interview. Salary is decent. Colleagues at my level are friendly and interesting people.
Cons
One of the flag values of Nielsen is "Transparency" but the common practice is to hide the true status of the progress not only from the client, but also from colleagues from other departments. When I shared info about lack of resources in my project as a cause for delay I was told by my manager "to wash the dirty laundry in my own house". Working hours are crazy. If you are not assertive they will make you work 7 am to 11 pm. People schedule calls at 3 am cause they cannot wait few days to talk to China. We outsource to India and I have heard of cases of people not sleeping there for 3 days to deliver. Forget about your own life....
