Does anyone know?

Hi there guys I have a interview over phone at a company in phoenix az but would be based out of Tucson where I live and its a food delivery service called shamrock foods. I had applied for a position driving a box truck and they finally called me asking if I would be interested in setting up phone interview. He told me I would be apart of a 2 year training where I would eventually get my cdl A driving a trailer. Anyone know about the company and what its like to work in the food delivery industry? I Currently have class b cdl so I want to get my class A I heard this company pays very well with great benefits.
