its a simple process, you apply with cv/ short application form, then a short 15-20 minute interview about skills/ qualities and past experience. I was 16 and had no past experience, so showing personality and being able to cover the hours needed is more important.

It was quick and straight to the point. Friendly interviewer who got to know you well, personable. Asked you questions about yourself and felt very welcoming. Quick feedback too on interview success or fail.
