Pros
This is a fun place to work if you're a high schooler. Getting to see and try new products before they hit the market is exciting and you can definitely feel like an "insider" at times. However they pay full time employees next to nothing.
Cons
I was working 80+ hours a week for next to nothing as an office manager. They don't care about their employees in the least and will fire you in a moment's notice for no reason at all. All of this so that Mary Cunningham can buy Hummers for her kids and continue being an overall terrible person. Additionally, they are notorious for fabricating the data they provide to clients. In other words, they make up fake people and submit survey data with their names when doing ACTUAL work is either too difficult or time consuming. Nielson Group - take note...half of those movie trailer surveys are made up. A horrid, disgusting hollow shell of a company.
