That's a tough one. It pays to read on here and any other sources online as well as checking a companies SMS scores. I was a student with JB Hunt in 1989.
It was free in exchange for working for them for a year.
I've never been unemployed since then.
I recently left Arnold after scoping for a company I could retire with. It took months of looking and reading and asking around. I'm so happy to leave Arnold in my rear-view mirror...
