Staffing agencies ultimately act and provide the human resource needs for their clients. These agencies manage and maintain thousands of resumes of applicants and job seekers. All function the same way, even though some are catered more toward a specific sector of the job market – providing a service matching job seekers to big or small companies and vice versa, finding qualified personnel who have the skills they need.

First, the staffing company would receive a list full of requirements provided by the clients of the job positions opened in their company that needs to be filled. With the description, the employment agency will create a job post and filter through potential applicants trying to find the right match for the client and the applicant.

The main focus for temp agencies is to match each applicant with a job. To achieve this, there will be an initial interview between the potential candidates and the staffing agency, which will help both sides get to know each other and see what type of a position applicants are looking for. To determine the candidate's ability to work in a specific position, the agency, in their initial interview, might ask the applicant to take a professional skills test, such as a typing test. These assessment tests give a staffing company an advantage matching the right applicant to the client, while showing proof to the client that the applicant's skills they introduce have been validated.

After the assessment tests, the staffing agency would set up an interview between the future employer and the employee once the staffing company believes they found the right client and applicant with an open position. There are two options when the employer is selecting a candidate. They can hire the applicant on a short-term or long-term basis like in the case with paralegal contract jobs.

If the client only wants to hire the applicant on a temporary basis, the employer will pay the staffing agency directly, who then pay the applicant on an agreed upon salary until he/she is hired permanently. After the agreed upon time set by both parties, most temp agencies will charge a one-time fee that the client will pay.
