It's important to think about how the position you are interviewing for will fit into your long term goals even as you apply for jobs. As you know, it takes a lot of hard work to become a personal trainer. You learn about the body, nutrition, fitness, and you learn about how people work, what motivates them. You may want to consider building your own business as you gain clientele. You might even want to study different forms of exercise or techniques that can help you in the field. Think critically about what you really want for your future and share how this role will benefit you by helping you get to the next step.
