You’ll typically start by submitting your resume and going through an interview process. During the interview process, the agency will review your resume and work to match you with job opportunities that fit your skills and experience.
Once they find a job opportunity that matches your skill set, they will send your resume to their client, and if they like your resume, the staffing agency will schedule an interview for you to meet with them. If the interview goes well and they offer you a job, you will then become an employee of the staffing agency!
