Distribution centre hiring near Pittsburgh - any advice?

A distribution centre near Pittsburgh is holding hiring sessions this week for packers, pickers and forklift operators. The posting lists shifts, a weekly pay schedule and overtime. 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.
