Warehouse hiring event in Honolulu this week, software tester here

A distribution centre near Honolulu is holding hiring sessions this week for packers, pickers and forklift operators. This is my first time dealing with any of this. They said to bring ID and a work history, and some people were hired on the spot. Do they hire temps first?

I applied for a similar job last year and the drug screen and background check took about a week. Bring two forms of ID.
