Everytime I get an interview, I think of questions they are likely to ask me. The hardest one I've ever done was "Tell me about yourself". They're not really looking for the amount of siblings you have or what your favorite hobby is (unless it is related to the job) so that would be a good one to think over. Try searching google. I spent a couple hours reading over some things and boy oh boy, did it ever help me on my interview.
