Confidentiality: Some job searches require a great deal of discretion. For example, you may want to explore an opportunity with one of your current group’s competitors. In such an instance, a recruiter can present your background confidentially.

Saves Time: Recruiters do the work for you. You can continue to focus on your current job while a recruiter conducts a job search for you. This is particularly helpful if you are relocating to a new city where you do not have professional contacts. Recruiters are thorough about assessing a job's requirements and your requirements, such as salary and benefits, so you don't have to worry about a job being right for you.

Hidden Job Leads: Even with all the Internet job boards, many positions are not publicly advertised or employers submit them as "confidential" directly to recruitment firms.

Presentation: It is hard to stand out in a stack of a dozen applications. Simply submitting a CV or application form leaves it up to the person reading it to figure out how you can add value to their organization. A recruiter can help “sell” your qualifications and answer questions about your work history. 

Interview Preparation: Acing an interview requires more than just having the right credentials. Recruiters can help you brush up on your interviewing skills. Additionally, they can offer an inside view of the hiring company and the people you'll meet during the interview.
