Distribution centre hiring near Chicago - any advice?

A logistics company in Chicago is adding people before the busy season. They said to bring ID and a work history, and some people were hired on the spot. Do they hire temps first?

Ask whether the job is direct hire or through an agency. The pay and benefits were very different for me.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
