I applied in-person. The process took 2 days. I interviewed at Ralph's Food Warehouse (Rio Piedras, PR) in Sept 2021
Interview
Nothing too difficult, basic customer interaction and some cashier math questions about counting money and giving change etc. They will accept most people, not too picky about their employees. Just listen carefully
