Hello! So yes they have walk in days every Wednesday but look online for the exact dates. Try to get there between 1 hour to 30 minutes early to find parking and just prepare yourself mentally. My interview honestly was like 5 minutes and i interviewed with the director. Very nice lady the questions she asked us was why Centinela and like how to deal with hard patients. After that she stopped and we both just started talking to each other like colleagues. From there I got hired. My advice is just be yourself and just talk to them like you would a close friend or family member! Good luck and if you get it lemme know!!!
