When searching for a staffing agency, make sure you understand the sectors the agency works in and if they provide temporary, temp-to-hire, or permanent jobs—or all three.
To identify reliable staffing agencies, use the American Staffing Association's web directory. You may look for businesses in your region. You may also search by industry and job alternatives (temporary, long-term, etc.).
Feel free to ask questions during your interview with a recruiting agency. Inquire about the perks they provide (if any), the kind of positions they generally fill, the sectors they deal with, and the average time it takes for a job seeker to get employment. Your recruiter is there to assist you, so don't be hesitant to acquire all of the information you need.
Investigate if the organization provides any services, such as courses to help you build skills or counselors to assist you with your resume and cover letter. Take advantage of them if they are accessible.
Remember that you should never have to pay a staffing firm to help you get work. Companies, not job seekers, pay reputable staffing services.
