What is an ATS and Why It Matters
An Applicant Tracking System (ATS) is software used by employers to automatically filter, rank, and manage job applications. Think of it as a digital gatekeeper that screens your resume before any human sees it.
Key Point:
Over 98% of Fortune 500 companies use ATS software, and 75% of resumes never reach human eyes due to ATS filtering. Your resume must be ATS-optimized to have any chance of success in today's job market.
Why Companies Use ATS
- Volume Management: Large companies receive 250+ applications per job posting
- Cost Efficiency: Reduces hiring costs by 30-50%
- Consistency: Standardizes the screening process
- Compliance: Helps maintain hiring compliance and documentation
- Speed: Processes applications 10x faster than manual review

How ATS Systems Actually Work
The ATS Process (Step-by-Step)
- Resume Parsing: ATS extracts text from your resume file and converts it into a structured database format
- Information Extraction: System identifies and categorizes information (contact details, work history, education, skills)
- Keyword Matching: Compares your resume content against job requirements and preferred qualifications
- Scoring Algorithm: Assigns a relevance score based on keyword matches, experience level, and other criteria
- Ranking: Ranks all applicants by score, with top candidates forwarded to recruiters
- Human Review: Only top-scoring resumes (usually top 10-20%) reach human recruiters
