Australian volunteer firefighter here with 10 years exp here.

I’d say all of us were all untrained normies when we joined who applied with an expression of interest (hi I’d like to join, I’m definitely not a fire bug). You get voted in and then do several hours of training every week for 6 months minimum before attending calls (grass fires, small incidents) then slowly upskill into MVAs (car accidents), house fires, rescues, medical Issues etc.

Not a great example, especially as nearly anyone can join and gain many skills from nothing without needing a resume let alone previous experience.
