I applied on indeed on their company site, and attached my cover letter and resume. I was contacted only days after about setting up a phone interview, which was pretty stress free and involved all the classic questions you'd expect to hear. She told me a little more about the job, how many days a week it would be and what hours, and went over what would happen at the internship.

Both fun and serious. Expect to be there for over an hour and speak with multiple people. Dress to impress and expect to shoot a basketball. Remind yourself what makes you fun, unique, and a good team player. Knowledge of professional sports is a huge plus.
