You firstly fill out an online questionnaire, this is reasonably difficult for people without prior knowledge of retail industry or for first time employees. It then says if you have been successful or not, if you have they should ring you back with in a week or two, I would advice to ring them after a couple of days (asking if theres any update on the application) and to keep on ringing them every few days/ week, this is because they often don't get back to you in my experience. I was then given an interview where I answered a couple of questions and was told they hire randomly and on your questionnaire score.
