Contrary to popular belief, a job interview isn't all about you. It's also a chance to learn about the ins and outs of the company you're hoping to join. Be prepared to zip your lips for minutes at a time or otherwise you may come across as domineering and needy. It's also important to be careful about the subjects you discuss. Although your interviewer will be interested in hearing about your past accomplishments and aspirations, they probably don't need to hear about your bearded lady fetish or the fact that you experience a burning sensation every time you pee.
