Phone screen first round, just 30 minutes over Skype doing basic behavioral. Then they flew out 40 people to NYC for a superday, consisting of four rounds. 1. Case—you're given a couple charts and graphs about a business, asked a question about that business. 30 Minutes to prepare a paper deck. 5 Minute presentation of your case, pretty simple, not a lot of questions asked by the interviewers. 2. HR interview—standard beavhioral questions, ask why you fit at Nielsen, "tell me a time when...", etc. 3. "Buy" interview—More analytical questions. Some market sizing stuff, and then brainstorming case style questions like "Coca Cola is trying to introduce a new product, what do they need to consider?" 4. "Watch" interview—Pretty behavioral, a couple questions about digital media and the entertainment industry, making sure you know your stuff
