Marketing careers and the various roles actually use a whole range of skillsets. There are people in marketing that spend most of their time analyzing data and stats. There are others who spend their time focusing on colors, shapes and names. And there are others like myself in sponsorships and experiential marketing who work alongside these folks to use sports teams, leagues and athletes to market our products and services.
Although the end product, and what you see in market might be a fun piece of creative, a video on social media, a free towel you receive at a game, just know there is a whole range of talented people behind the scenes that are looking at data, working on strategy, creating the visuals/experiences and ultimately helping to drive the business to reach its goals.
