Among many career counselors, the idea of plastering the town with 200 copies of an all-purpose re'sume' is a good way to waste time, money and energy. What may pay off faster is a re'sume' tailered especially for the job you are seeking. Which means, of course, you may be redoing your re'sume' (if only slightly) almost every time you apply.

And that, says career counselor Frances K. Bastress of Career Development Services in Bethesda, is one big reason for learning to write (and type) your own re'sume' rather than relying on somebody to do it for you. The rewrites and retypes could get costly.

A onetime personnel administrator, Bastress in her first job had to screen over 30,000 re'sume's a year. She became a strong believer in the targeted re'sume', indicating the writer had researched the company, rejecting those that weren't "relevant or oriented to a particular position." Because few large firms, she points out, have the capacity to keep quantities of re'sume's on file for any length of time they inevitably pitch them.

Another advantage for the do-it-yourselfer: "As an employer, we weren't interested in slick, assembly-line re'sume's. Rather, we were interested in the quality of the applicant. The applicant himself can convey this best. The third-party re'sume's soon began to look the same."

Besides, she adds, "It is useful for a job hunter to fully engage himself or herself in the self-assessment process necessary for the re'sume' development." Only the individual can probe his or her past "to uncover all past experiences as they relate to current job objectives." This self-awareness also comes in handy at the job interview. "You've gained a clearer picture of your qualifications."

Many job-seekers can benefit from books or classes on the techniques of writing an effective re'sume' that will catch an employer's attention. And it's always a good idea to show your draft to someone who can critique it for content, grammar and spelling.

GOING INTO BUSINESS?: Good advice is a useful commodity anytime, but particularly so when you are trying to start up a business.

Women who are considering self-employment (or who already have established their own firm) can arrange for an hour-long telephone counseling session with a business expert, often somebody in their own field. The service is being offered by the American Woman's Economic Development Corp. (AWED), a federally funded organization providing business training and technical assistance to women since 1977.

After contacting the group, the applicant will be asked to fill out a detailed questionnaire on plans and business background, and a phone appointment will be set. With this information in hand, the counselor--one of about 40 volunteers--can offer advice and answer questions. The fee is $25, and AWED picks up the cost of the long-distance call (funded by a grant from CBS).

Applicants have included doctors, lawyers, architects and other professionals who are trained in their fields but need business expertise to operate an office profitably, says volunteer Arthur Thompson, a management consultant. Most volunteers are male and have been in business for many years, ranging from their late thirties to well past retirement.

For women in business who need help immediately, there is a hotline. A volunteer will provide 10 minutes of toll-free counseling on a single question for a fee of $5.

To set up a counseling session, or to obtain information about the group's New York-based entrepreneurial training courses: phone 800-222-AWED or write AWED, 60 East 42nd St., New York City 10165. ------

SUMMER JOBS: The nation's camps, parks and summer resorts are traditionally a major source of seasonal jobs for college students and teachers. When the paying guests begin pouring in, somebody's got to serve them. Even in today's economy, openings apparently are still available, though employers are expected to be more selective in their hiring.

The jobs, lasting normally from Memorial Day to Labor Day, range from housekeeping and kitchen chores to counseling, physical therapy, sports and crafts instruction to resort management. The pay, generally for six days a week, may be anywhere from $600 to $2,000 for the summer, with food and lodging provided. Many places offer such fringe benefits as health insurance and cost of getting to the work site.

One of the most comprehensive lists of what's available can be found in the 1983 Summer Employment Directory for the United States (Writer's Digest books, 232 pages, $8.95), first published in 1952. It is available in many bookstores, libraries and high-school and college career-counseling offices.

The book details more than 700 employers, two-thirds of them camps and resorts, with an estimated 50,000 summer openings, says editor Barbara Kuroff. There's a description of the camps, what they pay and distance from the nearest town or city when you want to get out of the woods.

New in the latest edition are guides to getting seasonal work in banking, hospitals, newspapers and utilities, among other home-town industries, written by professionals in each field. In Washington, where government is the industry, the National Park Service, for example, is seeking about 10 graduate-level architectural students for summer work as architectural historians. The Park Service, however, already has been flooded with applicants.

From what employers tell Kurloff, job-seekers should pay attention to neatness when submitting an application for summer work. "Be creative" in your search, she adds, and if you can find something that will further your career goals, so much the better. For example, theology students, destined to be counselors in time of crisis, frequently seek hospital jobs.

One final caution: You should have started looking during Christmas, but spring break is not too late.
