What Is an Applicant Tracking System?

An Applicant Tracking System (ATS) is software used by employers to automate the recruitment process. It collects, organizes, and filters job applications based on specific criteria such as keywords, skills, experience, and qualifications.

Why Employers Use ATS

• Standardize candidate evaluation
• Reduce hiring time and costs

How ATS Affects Your Resume

ATS software scans your resume and assigns it a relevance score. If your resume doesn’t match the job description closely enough, it may be rejected automatically.

A well-written cover letter can also boost your chances. Check out these health promotion cover letter examples to see how targeted applications work in practice.
