Hiring several warehouse roles around Phoenix (update)

A distribution centre near Phoenix is holding hiring sessions this week for packers, pickers and forklift operators. This is my first time dealing with any of this. The posting lists shifts, a weekly pay schedule and overtime. What are the shifts like?

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
