I worked at Guardsmark full-time (More than 10 years)
Family environment good support and helpful management
Pay was too low to attract quality personnel
I applied online. The process took 4 days. I interviewed at Guardsmark (Wichita, KS).
Walked into an office, sat down, asked a bunch of questions and then give you a bunch of paperwork and a DVD full of stuff you have to review for the paperwork questions. Once it's over they will most likely have you go to a drug test.
There wasn't one. They told me the pay and I agreed. Needed a job so whatever they were offering was good to me.
