Would BestBuy hire me without work experience?

Hi! I am a college student looking for a first job for work experience ( and of course some money). Best Buy is a place I am heavily considering applying to as I find tech interesting and I feel like sales for it would be fun. So is BestBuy selective in their hiring? Or if I do well enough on the interview can I score a job here?

P.S Do I have to be extremely knowledgeable in what I am selling, or will I be trained on that?
