I wish I could have met Daria before Daria met her husband
Seriously: One is not going to be "fully qualified" for most jobs upon beginning said job. Some sort of training is invariably required, as said job always has specific characteristics not found in any other job.
Invariably, upon starting any job, one is a veritable "greenhorn."
It should be remembered, though, that many "greenhorns" (immigrants) attained, to a large extent, the American Dream (or equivalent).
I remember one job I applied for. They wanted sort of a link between the developers and support. This person would be delegating tasks, prioritizing them, etc... So in reality this person should know just about everything about the whole system. I asked them if there was a training period. Their answer was "no".
