TOPSHOP/ TOPMAN interview tips please anyone please?

I work in my local one as a sales assisant. Basic trends is all you'll need to know, so like the 60s/70s vinatage feel, lots of shift dresses in bright colours, colour blocking, wedges, white, lots of florals and girlie things edged up by pale denim and leather jackets. Everyone at mine had to pick out a full outfit or two- just a clue, its all done in sections called a trend, so things will work better together if they are all from that trend. And then just stuff like have you done anything like it before, are you confident talking to customers and giving advice on things- it kinda vaires between store but you get my drift. Wear something smart but stylish, if you can get to a store and see the kind of things the sales advisors wear already then that'd be your best help, if you have the kind of chino trousers and a sheer shirt or nice top then something like that?
