I applied in-person. The process took 2 weeks. I interviewed at Gold's Gym SoCal (Anaheim, CA) in Feb 2020
Interview
2 parts, 1st initial (classic/typical, question/answer interview) and then the 2nd is the skills portion where you take the manager through a workout. Basically just to test out real life skills and see how much you know. See if you can take someone through safety and know how to properly correct the client's movements.
Interview questions [1]
Question 1
"Why do you want to work here?"
Asks about past experience.
Asks about future goals and availability
