Schneider National Truck Driver Question?

Ok so, i have a CDL and have only about 1.5 months experience driving a tractor trailer. I haven’t driven one in 2 years since i’ve been working in a different kind of career. But i’m having a hard time making enough money to pay for my food, gas, etc and also afford an apartment/utilities.
So i’m planning on going back to the trucking business since there i didn’t have to worry about rent and utlities.
I don’t want to return to my old company. Instead, i’ve been seeing Schneider’s ads in the paper and am thinking about going that route.
1 — Now, will i be sent to one of their schools and be tested on my ability to park, drive, etc. OR will they put me on a truck immediately with a trainer ?
2 — How hard is their physical test during orientation. I don’t know what they would call it but it’s where you show your ability to lift properly upto 75 lbs at different heights.
3 — How often will i get touch freight and is it usually hand unload or using dolleys and carts ?
