Despite conventional wisdom, you do not want to start your job search with a major resume effort. To do this puts the cart before the horse. A resume is really a kind of ad or brochure. Before developing an ad campaign, an advertising agency carefully targets its market and defines its customers' needs and priorities. Only after identifying these factors, does the copywriter describe features and benefits most useful to the targeted market. In your case, you are the product. You bear the responsibility of selling your most important experiences and attributes to potential employers on a person-to-person basis. If you write your resume before you have found out what they need, you are missing an opportunity to present your best case.

Resume search is important for the job interview, too. Most of us are more comfortable moving into unfamiliar territory if we have a map of the terrain. When you have researched an individual company to tailor your resume, you know a great deal about its products-- services, mission, philosophy, revenues, and so forth. This information can be very valuable in preparing good questions and answers for initial and subsequent interviews. Employers like candidates who are savvy enough to do some homework before their first meeting. In customizing your resume, you are pursuing two objectives simultaneously: You are creating a powerful written sales tool, and you are developing a verbal testament about why a specific employer should hire you. If you think of your resume-writing process as the best preparation for a rigorous interview session, you will be more likely to give it the time it deserves.
