I applied in-person. The process took 2 days. I interviewed at Stevens Aviation (Greer, SC) in May 2015
Interview
You would have to go into the FBO and talk to one of the counter girls, once you specify that you would like to apply for a job, they will make you fill out an application on site and you would usually get a call the same day.
Interview questions [1]
Question 1
They are usually very short on people so you will probably get hired on the spot, regardless of experience.
