Hiring several warehouse roles around San Diego, school bus driver here

A distribution centre near San Diego is holding hiring sessions this week for packers, pickers and forklift operators. There are 4 people counting on me, so I am trying to be careful. 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 12 months ago, and it got easier once I kept a simple log of every call and form.
