Do Company's like Challenger and Schnider do licence training?

I'm looking to do long haul for a living and i seen on challengers website the do training for 6 weeks. I'm going to do my Z but do I need to go to a driving school go get my A or do "big name" company's train you for the A. May sound stupid just need some clarification before i start to apply for jobs/school?

Maybe because younger people now a days prefer less interaction. I'm just looking for someone to help me get the 2 years experience every respectable well paying job requires. From what I have read on these forums the bigger name company's are becoming more of a stepping stone to get where the vets are. I know the job isnt the most glamorous but from what ive read and what my grandfathers have told me there's a big difference coming out of the gate working long hours/minimum wages and owning your truck and getting first picking hours and loads because of your record and experience and ect. Im looking for a company that will help me with the A training and get me on the road for a future career in long haul.
