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.

was structured as a group interview so there were a few of us, interviewer explained what work is like and showed us the warehouse floor. was all very relaxed and didn’t have the pressure of a regular interview
