Employers that hire people with a record, Oklahoma City - any advice?

A few employers in Oklahoma City say they hire people with a record, including a manufacturer and a warehouse. There are 9 people counting on me, so I am trying to be careful. Pay starts at an hourly rate with benefits after 9 months. Has anyone worked at these places?

Be honest, brief and forward-looking when you talk about it. They care more about what you did since.
