Both employers and candidates should be attentive to the professionalism shown by an agency. Unprofessional behavior may be taken as a sign that their professionalism is lacking in other areas as well. If they exhibit unprofessional behavior, it may be better to opt for another agency.
Applicants should find out whether the agency offers the type of IT job the applicant wants. Sometimes, an agency recruits workers from a limited area within the IT field only. It may be best to find an agency that recruits in one specific area.
It is best to choose an agency with more years of experience. Ask how long the IT recruitment agency has been in business.
It is a good practice to stay away from any agency that wants its applicants to register with them only. However, agencies should be notified that the applicant is registering elsewhere. You should limit the agencies you apply to.
Prospective IT workers should ask the agency about its record of finding jobs for other applicants who work in the same area of specialization.
Research the agency to see how previous applicants feel about them.
A recruitment agency should not require money from job applicants. If the agency requests money, it is a sign that it might not be a legitimate agency.
