Interviews are a chance for you to show off how well-informed and prepared you are. It's good to appear that you know what you're talking about; it's even better to appear that you're competent enough to learn more; but most of all, it's good to appear to care and to be enthusiastic about the job! When you're looking for a job, you need to do three kinds of research:

• Research the industry
• Research the company
• Research the position

There are also a few good sources of information.
