Interview advice

Ive got an interview for a QA testing job in a games development company. Its my second in fact as they have got a hard choice of who to pick between me and i assume another person. Anyone give me any advice especially related to QA testing. I must be pretty good if they wanted to choose between me and another person, so just general advice would be greatly appriciated. Thanxs!
Do your research. Know something about the company and their product(?). Be knowledgable (or at least try to appear so) about any equipt you may use in the job. And mention something about the companies accomplishments.
