Not that I know of as they never did one with me.
Sometimes they do but they take anyone due to the fact everyone leaves.
Was 16 when i joined i didn't do this.
CVs and cover letters required as well as online application. No ex-staff are considered for employment, as well as under 18s and students being avoided.
They do, and it can vary
Criminal background checks
Might do some reference checks if they feel like it
