The recruiter has a responsibility to the employer. He or she is, in fact, representing the employer's interest when they interview you. Treat the recruiter with the same respect, integrity and professionalism that you would want to present to a prospective employer. Be honest, positive, knowledgeable and confident. You will want to treat the recruiter much like you would a confidante because the more the recruiter knows about you, the easier it will be for her to find the right position for you.
Recruiters make great advisors and mentors.
You can learn a great deal from their knowledge of companies currently hiring, their network of contacts, and their expertise in career planning. The recruiter makes his or her salary by successfully filling a position. Usually this means that some or all of the expenses incurred are the recruiter's responsibility. Time is important to recruiters. So is their relationships with employers.
