Interview questions [1]
Question 1
Interviewer asked how much experience training, what my interests are, and what certifications I had. Two or three role-play scenarios where I was asked how I would train clients with certain pre-existing health conditions or to prepare for a specific type of sport like football.
I applied in-person. The process took 1 week. I interviewed at LA Fitness (Oviedo, FL) in Feb 2008
Interview
One of the simplist interview processes. I went there, asked if they were hiring... said they were accepting applications. I filled one out and a couple days later got a call from the head of personal training department. He asked a few questions and scheduled a face to face interview a few days later. I don't remember exactly how it went but it was pretty easy. A few days later he called me back and offered me the opportunity after discussing with manager. I started working the next day.
