I applied in-person. The process took 1 day. I interviewed at Planet Fitness (Evergreen Park, IL) in Jan 2012
Interview
The gym hadn't opened yet, they had a small booth set up to sell memberships before they opened. I did a Walk-In and dropped off my resume. I received a call the next day saying I got the job, I never received an interview.

Question 1
There was nothing difficult, I was hired on the spot and didn't have any problems getting the job.
