ATS (Applicant Tracking System) — a robot that reads your resume before any human sees it. In 95% of large Indian companies (TCS, Infosys, Wipro, Reliance), 80% of MNCs in India, and increasingly even in mid-size firms, your resume first goes through ATS — and if it fails, HR never sees it. Let\'s break down how ATS works, how to pass the filter, and 5 typical mistakes that automatically reject candidates.
How ATS works
ATS is software that:
- Parses resume — extracts text from PDF/DOCX
- Structures by sections — contact, experience, education, skills
- Ranks — compares with job description, calculates keyword match
- Filters — resumes below threshold (often 50%) don\'t reach HR
Popular ATS in India
- Naukri.com Recruiter — built-in ATS for India\'s biggest job board
- LinkedIn Recruiter — for global Indian companies
- Workday — large MNCs (Microsoft India, Amazon India)
- Greenhouse — tech startups (Razorpay, Zerodha)
- Lever — SaaS companies in India
- Taleo (Oracle) — legacy but still many enterprises
- iCIMS, JobDiva — staffing agencies
5 mistakes ATS rejects
1. PDF with scanned text
You printed resume, signed by hand, scanned and sent PDF. ATS can\'t read scanned text — bot sees "image" only. Fix: export PDF from Word/Google Docs (text-based, not OCR).
2. Tables and columns
ATS reads document top-to-bottom, left-to-right. Two-column resume = chaos. Fix: single column.
3. Graphics instead of text
Skill progress bars, icons, diagrams — ATS ignores. Your skills will "disappear". Fix: text list.
4. Non-standard fonts
Gothic, handwritten, "designer" fonts get distorted in parsing: "Python" becomes "Pythom". Fix: Calibri, Arial, Helvetica, Georgia.
5. Wrong heading names
Instead of "Work", "Career", "Positions" — write "Work Experience" or "Experience". ATS searches for specific section names.
Ideal ATS-friendly format
- File format: PDF or DOCX (not scanned)
- Layout: single column
- Font: Calibri / Arial / Helvetica, 11pt body
- Headings: standard ("Experience", "Education", "Skills")
- No tables, no graphics, no photo in critical sections
- Keywords from job description — 7-12 items, naturally distributed
- Dates in MM/YYYY format (not "three years ago")
- File name: Latin alphabet, Surname_Name_Resume.pdf
How to test your ATS-score
Online checkers:
- Jobscan (jobscan.co) — free trial, detailed report
- Resume Worded (resumeworded.com) — full free plan
- Enhancv ATS Checker — quick check
- Simple test: copy text into Notepad. If formatting preserved — ATS will read.
India-specific tips
- Naukri.com profile sync — fill out profile in detail; if recruiter searches Naukri database, your profile is the "resume"
- LinkedIn keyword density — Indian recruiters often pull from LinkedIn first; same ATS principles apply
- Company-specific keywords — "Tally", "GST", "TDS" for finance roles; "Selenium", "JIRA" for QA — match exact terms from job description
- English level mention — "English (IELTS 7.5)" or "English fluent" — ATS may match keyword "fluent"
