Basic CV and cover letter application - and then if successful, you'll be invited to a group interview. Dependent on the store - the group interview could consist of around 25-55 interviewees. You have to undertake numerous group activities, and do some solo-presenting. If you are successful, you'll be invited to a trial shift. This won't consist of many 1-1 questions, you'll mainly just be put onto the shop floor. It does feel like being thrown in at the deep end a bit - I suggest doing some product research so you know what to talk to customers about. Demo lots of products, if appropriate, in your consultations.
