OT HELP: Best Prep for Derivative Sales (Analyst) Interview

Hey guys I have a problem: A derivative sales interview is scheduled for next week. And I have no clue about derivatives. Is there anything available on the web to brush up my knowledge? Of course, google has 1000 hits, but a recommendation would be great. What can I expect at an interview for an analyst position (equity derivative sales)? Every input is very much appreciated!!! Thanks guys… alex
