I applied online. I interviewed at Crunch Fitness (New York, NY) in Feb 2022
Interview
It was normal , ask about your goals and why you would be a good fit here. Also they asked about past experience in the fitness & health field.they also asked about my personality.
Easy to the point but wanted sales features added in. I did not move forward after they asked questions because of this. Overall easy process and generally friendly. Interview was with two people including manager
I applied online. The process took 5 days. I interviewed at Crunch Fitness (Louisville, KY) in Mar 2022
Interview
In-person, quick, not formal. Got a call then came in to interview. They opened a new location and were looking to fill spots. Best time to interview because they hire anyone.
