Know a little about the job you are applying for. I hate interviewing people and they don't even know what the business does. The internet has job interview questions, print some off and practice with friends or family. Maybe tape the practice interview so you can see if you are doing something wrong. Dress nice. It really is hard with the economy, so some people here are taking jobs in temp agencies hoping it leads to full time work. They showed a guy on the news who is a PHD and is bagging groceries. One man had 3 degrees and speaks 3 languages and he has a job as a janitor. They had a job fair for a business and 600 people applied for the three jobs available. It is tough, good luck.
