Warehouse hiring event in Pittsburgh this week (Pittsburgh)

I saw a flyer for warehouse hiring on the east side of Pittsburgh, with day and night shifts. 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. What are the shifts like?

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

Night shifts often pay a premium, but check the transport options first. The buses thin out late.
