From the first encounter, other employees or applicants want all the attention and the training.
First interview, people saying they want this job and will do anything for it.
In training, talking over you and then coercively telling others not to talk to the one who knows more the they do, because, that isn't fair.
Trainer on the floor of the team poor communicator, in transition with no time to train everyone. Favors the ones who caught on in basic training, so get the boxing gloves ready, you will need them.
