Poor training, manipulative tactics. You won't ever be told to do something as part of training but gods help you if you mess it up after you're left to wing it, and you absolutely can't ask to get paid for the time you spend trying to muddle through it after not being trained on how (or the time you spend fixing it when they tell you it's not right). Payroll will not care when they mess up your pay. You cannot start full-time, and good luck getting what you're verbally promised, because it will definitely be reduced many times over before you can convince them to put it to paper.
