I had an interview at my local Primark last week. They will show you pictures of poor chinese and indonesian workers and children, they will then ask you how you should treat these people. Apparently i didn't get employed because i got this question wrong, but i spoke to someone afterwards and they said i was meant to say i would treat them like dirt, pay them pennies and force the children to work unpaid overtime.
I've worked there for about year and a half (weekends), my interview was really easy, they were really friendly and basically told me what to say to answer each question. I think if you have an interview you've pretty much got the job, but don't hold me to that :P Good luck
