What Is an ATS and Why Does It Matter for Your Job Search

If you have ever applied to a job online and never heard back, there is a good chance your resume was filtered by an ATS before a human ever saw it.

What is an ATS?

ATS stands for Applicant Tracking System. It is software that companies use to manage job applications. Major ATS platforms include Greenhouse, Lever, Workday, Ashby, and iCIMS.

When you apply to a job, your resume goes into the ATS first. The system parses your resume, extracts information, and scores it against the job description.

How does it filter resumes?

The ATS looks for keyword matches between your resume and the job posting. If the job asks for "cross-functional collaboration" and your resume says "worked with other teams," the system may not recognize the match.

It also looks for:

• Job titles that match or are similar to the role
• Skills mentioned in the job description
• Years of experience in relevant areas
• Education requirements

If your resume does not score high enough, it gets filtered out. The recruiter never sees it.

The numbers

• 75% of resumes are rejected by ATS before a human reviews them
• Tailored resumes get 1.6x more responses than generic ones (5.8% vs 3.7%)
• The average corporate job gets 250 applications — ATS helps recruiters manage the volume

How to get past the ATS

1. Mirror the job description. Use the same keywords and phrases they use.
2. Use standard formatting. Avoid tables, columns, and graphics that ATS cannot parse.
3. Include a skills section. List the specific technologies, tools, and competencies from the job posting.
4. Tailor for each role. A generic resume scores low against every job description.
