Company seemed very professional. They have a series of interviews asking a lot about interest in Nielsen...if you don't know anything about the company or what they do, they will most likely remove you from the application pool. In my analyst class, I saw kids from lesser-known schools getting offers over some of my friends from Ivy League universities. The most important part of your interview is to be very knowledgeable about the Nielsen website and your specific position. They don't ask any challenging questions, culture is not like finance in this firm. Very relaxed and laid back.
