Job Interview.....

i have a job interview at future shop (sells home appliances, audio, video, etc.)...well similar to Best Buy in the states and best buy bought future shop (which was canadian owned)..and was wondering if you have worked at either Future Shop (for Canadian people) or Best Buy (for U.S. people) and what kind of questions they ask in the interview and what they look for.

if you kno..can you tell me...it'll be a big help..
cuz i'm always nervous during job interviews...
