I applied in-person. The process took 1 day. I interviewed at Puerto Vallarta (Graham, WA) in Sep 2018
Interview
Walked in, asked for a job, and was immediately led to the dishwashing area. They asked the other dishwasher to show me what to do, and then left me to work. It was that simple. The work itself I guess was the trial period/interview since they asked me to come again.
