If you are seeking employment in a specific industry, consider using a headhunter who works in that industry. If you belong to a professional association they may be able to provide a list of recruiters.
Use recruiting online directories to generate a list of recruiters. The Recruiters Online database is searchable by over 150 specialties, as well as by location and keyword. Jobfactory also has listings by career field, while i-Recruit.com has an directory of recruiters listed by specialty and by location. Check our Headhunter Directory for more directories.
Network with business colleagues and acquaintances to get suggestions.
Turn the table and spend some time interviewing the recruiter. This is an important professional relationship and you need to be sure it's going to work. Ask how long the recruiter has been with the company. Also ask how about the process and how they market your resume and present it to potential employers.
Ask the recruiter for references and check them. Talk to clients about the services that were provided and what they thought of them. Also, ask if they would use the recruiter again.
Finally, make sure you are comfortable with both the company and the individual. There needs to be a fit between your style and the style of the people who are representing you.
Remember, that using a recruiter should only be one step in your job search. There is no guarantee if, or when, a lead will turn into a job offer. So, do not stop your own job search efforts and don't stop networking or looking for potential opportunities on your own. Do let the recruiter know that you are seeking other opportunities.
