Unless you are able to bypass the Applicant Tracking System, or ATS, an employer will never even see your resume. An ATS is a system designed to sort and filter candidates based on qualifications for a position that are provided in resumes and cover letters. These systems make the hiring process more manageable for employers as they get hundreds of resumes per day by sorting through the ones that contain very little relevant information for the job. These systems make it imperative to customize your resume for each job and utilize critical keywords as they pertain to the job.
