I applied online. The process took 2 months. I interviewed at Los Angeles County (Los Angeles, CA) in Feb 2017
Interview
Very straight forward with basic questions for troubleshooting issues, locations of support and troubleshooting programs, etc. Had one interview have to role-play assisting a person who's system couldn't connect to the internet, and another interview I was asked a variety of questions, from what is the control panel, etc.
