What has made you such a successful marketer?
The interviewer is trying to assess what makes you uniquely qualified for the job. They want to know that you understand what the position entails and have confidence in your ability to do the job. They'll likely see how your answers match up to your resume and cover letter.
Offer your perspective on what marketing means to you. Detail your track record for delivering and how your point of view sets you apart.
"I understand what captures people's attention. Everyone is an individual and craves sincere interactions. No one wants a fly's attention. A random pop-up ad is like the fly. Most people swat it away. But when someone you admire stops everything to engage with you, that's different. The goal is to reduce cost and advertise to the aggregate, yet make it individualized. To do that, capitalize on universal truths. When one person sees others flocking towards opportunity, it's instinctual. Whether it's hunter-gatherers flocking to a bountiful food source or hundred-dollar bills floating from the sky, the aggregate behavior kicks in. That's my outlook, and it's worked for me pretty well so far."
Don't say, "Because I'm the best in my field out of anyone I've ever met. In fact, I'm probably be best that's ever lived." It's fine to share your accomplishments and exude confidence, but avoid self-aggrandizing and bragging.
