TemperatureCheap1280's journey

I recently became a certified personal trainer in February and have been actively searching for my first job in the field. At 26 years old, I come from a background in martial arts and running, but I haven't had the chance to train anyone yet. I've applied to around 100 positions, including places like Planet Fitness, which typically don't require prior experience. Despite landing several interviews, I haven't received any offers, and I'm starting to feel stuck. I suspect that my vibe or how I present myself during interviews might be affecting my chances. I'm feeling a bit lost and would appreciate any advice or insights on how to improve my job search.
