Tesco interview

Hey guys,
I have been called in for a interview at tesco and i am pretty nervous. Any ideas what questions they ask? And what should i wear?
Any information is much appreciated

i wore just a black pair of vans, plain black trousers and a plain shirt.

i only had a few question in mine since it was pretty informal

why do you want to work here?

any experience in retail? i said no but i pick stuff up easy etc which they seemed to like.

and then they just briefly talked about the role etc and that was that.

Wear everything from tesco.

Walk into the room and shout 'EVERY LITTLE HELPS'

You have the job.
