Female Secretary Question:

Prepare in advance, and in a word, research, so, you can provide relevant and current information about your prospective employer to the interviewer. Start by researching the company online. Review the "About Us" section of the company web site. Google the company, read blogs that mention it, and check Discussion Boards and social networking sites.
Use the information you have gathered to create a bulleted list of relevant information that you can easily remember during the interview. Taking the time to research will help you make a good impression with how much you know about the company.
