I talked to Nielsen for the first time at my universities' career fair. I didn't really expect to get a call back or even less an interview. A few days later I was called by a recruiter to set up an on campus interview. The first interview was really hard. I was hit with all sorts of questions from your typical behavioral questions to really technical one's. The interview lasted about an hour and was done by two recruiters. A few days later I got a a phone call from Nielsen inviting to second round interviews in Tampa, FL. It was held at a very nice resort. There was a full day of interviews 7:30AM to 2PM. I interviewed a total of 3 times with 2 managers each time. After the interviews the VP of their Global Business Unit was in town and stopped by to give a key note speech and I thought it was really cool of how much exposure you have just as a candidate for the job.

Behavioral Based Interview that took place on my college campus, we were in a large union room with multiple other interviews going on at once, so you had to make sure to pay attention to your interview and try and block out the background noise, it also made it more relaxed though
