Hiring several warehouse roles around Denver

A distribution centre near Denver 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. What are the shifts like?

If you have forklift experience, say so. It moved me to the top of the pile.

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