I applied online. The process took 1 week. I interviewed at ADT (Los Angeles, CA) in Jan 2018
Interview
Three interviews in total. First was a phone call, second was a skype interview, and the final was in their LA corporate office. It was overall not too difficult, in the second interview they ask you the four P's of marketing and to sell them a pen.
