Ride alongs and multiple interviews. More time consuming than you'd expect, but worth the effort as it results in dedicated, competent staffing. They'll make sure you're a fit for the job, which isn't for everyone due to the physical, high energy and thorough nature of the day to day activities.

first you will do a ride-along with another SSR then return to be interviewed. 3 interview process 1 with HR, 1 with lower level managers, and 1 with the general manager
