Interview Question for Professional Services Intern at The Nielsen Company:

Case study: You are a senior project manager with the option to choose one of two clients for your next project: Client A, whose brand A has a very broad customer base consisting of customers who buy Brand A infrequently. Client B, whose brand B has a much smaller but more loyal customer base. If you had enough resources to conduct research for only one brand, which would you pick (and believe will be most successful), and why?
