Aloha bra,
It's not impossible to get a 9-1-1 EMT job in Southern California but you have to know your stuff. The process for myself has taken about a month to turn in application, take their tests, and now I am in the interview processes with companies. All three 9-1-1 companies I have applied to I've gotten interviews with, but I do have some background in first responding being a former Lifeguard.
