Distribution centre hiring near Tampa (update)

A distribution centre near Tampa is holding hiring sessions this week for packers, pickers and forklift operators. I have read a lot of threads here and could not find my exact situation. 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.
