I applied in-person. I interviewed at Axiom Fitness (Boise, ID) in Feb 2015
Interview
You will interview with the manager at the location you are interested in working at, and then you have to interview with upper management. For me, her name was Annie. She was obviously very unfriendly and miserable in her job.
Interview questions [1]
Question 1
Lots of questions about how you would work with kids, your experience with kids, how you work with difficult people.
