You'll either get a phone call saying to come into work, Or you won't.
If and when you come into work they will break down the whole process step by step, Give you a bank, Uniform, And a sign for your car.
You'll get a once over on how to do everything, From there you'll be expected to learn on your own how to do everything else.
(Pro-tip, Befriend the most senior driver after about 2 days of showing that you're there to work hard.)
