Since you're interviewing for an entry level position, you aren't required to have experience in the industry. What will help is having transferable skills in which you have experience dealing face-to-face with customers, clients, etc. I learned that pretty quickly during the second interview where I had the opportunity to speak with one of the Senior Account Managers. During the rest of the interviews, you'll probably meet a few different members of the staff, but don't be intimidated. They don't expect you to know everything, but they do expect you to want to learn and be goal-oriented with your career. If those things are there, and you think the company could be a good fit, you've got a really good shot at getting hired.
