none as it was from agency and went to work to show how I was willing to work and that how I can do the job properly and efficiently. I got the job done and could come back.

Very simple. A quick chat with the agency about role expectations, followed by an in-person chat which was more of the same really. "Can you lift X amount?" "Can you work X amount of days/hours?" "What experience do you have?" are the sort of questions to expect.
