Complete guide to applicant tracking systems (ATS)
Master ATS optimization and multiply your chances of landing interviews
What is an applicant tracking system?
An Applicant Tracking System (ATS) is software that employers use to process the overwhelming number of applications they receive. It stores all candidate information, tracks hiring progress, and helps recruiters quickly identify qualified candidates without reading every resume manually.
Here's the critical part: recruiters use the ATS to search for resumes using specific keywords. If your resume doesn't contain those keywords, it may never be seen by a human recruiter — no matter how qualified you are.

How recruiters use ATS to find candidates
According to Jobscan surveys, recruiters search the ATS database using these filters (in order of importance):
76.4% filter by skills from the job description
59.7% filter by education level or degree
55.3% filter by job title match
50.6% filter by certifications or licenses
44.3% filter by years of experience
43.4% filter by location
If your resume doesn't include these key elements that match the job description, it won't show up in recruiter searches.
Proven ATS optimization strategies
Follow these proven strategies to optimize your resume for ATS:
1. Add the Exact Job Title from the Posting
Place the exact job title from the job posting at the top of your resume. This is the #1 most impactful optimization — resumes with the job title receive 10.6x more interview requests.
2. Mirror Job Description Keywords Naturally
Copy-paste the job description into a document and highlight key skills, tools, and requirements. Incorporate these exact keywords naturally into your resume, especially in experience descriptions and skills sections. Don't just list keywords—use them in context.
3. Build a Comprehensive Skills Section
76.4% of recruiters filter by skills first. Create a dedicated skills section with both technical skills and relevant soft skills. Always include both the full name and acronym (e.g., 'Applicant Tracking System (ATS)', 'Customer Relationship Management (CRM)').
4. Quantify Your Achievements
Use numbers, percentages, and metrics to describe your accomplishments. Instead of 'managed a team', write 'led a team of 12 engineers'. ATS can parse numbers, and they make your resume more compelling to human recruiters.
5. Use Standard Section Headers Only
Stick to conventional headers: 'Work Experience', 'Education', 'Skills', 'Certifications'. Never use creative headers like 'My Journey' or 'What I Bring' — ATS systems are trained on standard terminology and won't recognize custom headers.
6. Avoid Complex Formatting
No tables, graphics, logos, or special characters (★, •, ◆). Use simple bullet points (- or •), standard fonts, and clear spacing. TypstMe templates are already optimized for this.
7. Format Dates Consistently
Use the same date format everywhere: 'Jan 2023 - Dec 2024' or 'January 2023 - December 2024'. Inconsistent dates confuse ATS parsing and can lead to incorrect experience calculations.
8. Provide Context with Action Verbs
Start each bullet point with strong action verbs (led, developed, implemented, increased, reduced). Follow with the action, the tool/skill used, and the result. This structure helps both ATS and human readers.
9. Customize Your Resume for Every Job
Never send the same resume twice. According to recruiters, generic resumes have a 2-5% response rate, while tailored resumes have a 15-30% response rate. Spend 15-20 minutes customizing for each application.
10. Proofread for Typos and Consistency
ATS with AI can detect inconsistencies (e.g., claiming 10 years of experience but first job started 5 years ago). Double-check all dates, company names, and job titles match your LinkedIn profile.
Understanding knockout questions
Before your resume enters the ATS, you might encounter 'knockout questions' — automated questions that can disqualify you immediately if answered incorrectly. These are programmed by humans, not the ATS itself.
Common knockout questions:
- Are you willing to relocate?
- Are you willing to travel?
- Are you willing to work full-time?
- Do you have X years of experience?
- Do you have [specific degree or certification]?
💡 Tip: Answer honestly but strategically. One wrong answer here can eliminate you before anyone reads your resume.
What is a resume score?
Many ATS platforms (like Oracle Taleo) rank resumes based on how closely they match the job description. Your score is calculated from your entire resume — experience, skills, education, and more.
The higher your score, the more likely you are to land an interview. To increase your score, identify the most frequently mentioned keywords in the job description and incorporate them naturally into your resume.
