"In my opinion, an effective marketing team is made up of individuals with unique skill sets and varying levels of experience. I like to know that I can learn from those around me and that I will also have the opportunity to teach my skills to someone else. When this diversity is present, very creative ideas flow and effective marketing campaigns can be executed with excitement."

First, acknowledge that there are many ways for a marketing team to work effectively and succeed. If you have been part of a talented marketing team, explain what made your experience so enjoyable and what made the team effective as a whole. If you haven't been part of a great team, you can simply share your opinion on what makes a team successful. Hint: Look to the job ad for clues about what the company's marketing team is like, and craft your answer based on that.
