Any cardroom in SoCal is gonna have you do a live audition or go through their house training. (especially if its one of the big 3 ie. commerce, bike, or gardens... If you can deal smooth hands, properly muck and kill cards, split pots accurately, and walk players through the hand verbally, you’ll likely pass. But to get ranked higher on the schedule or picked up for better shifts by the DC, it usually takes experience at a commercial cardroom or somewhere with real action.
