Normally, you go to the customer service desk and there will be someone waiting for you there. Primark plans all their job interviews on 1 day. The person will take you to the back office and you will be interviewed by someone from HR or a manager. They have a standard paper with questions they ask, but it's really basic stuff. Present yourself and then come the questions about Primark. Takes about 15 minutes total. I was told I was going to get an e-mail in 1 week max.
