Distribution centre hiring near St. Louis - 8 weeks in

I saw a flyer for warehouse hiring on the east side of St. Louis, with day and night shifts. There are 3 people counting on me, so I am trying to be careful. 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.
