I applied online. The process took 3 days. I interviewed at Action Duct Cleaning (Altadena, CA) in Dec 2016
Interview
You will meet with their Office manager and GM first. If they approve, you'll then be called back for a 2nd interview with the owner. They will require a background check and upon successful completion you'll be offered a job.
Interview questions [1]
Question 1
They want to know mostly about your integrity and beliefs. I don't think they care much about past work experience to be honest.
