How to Make Your Resume ATS-Friendly

ATS (Applicant Tracking System) is a software application that automates the recruitment process for employers. It streamlines sorting, scanning, and ranking job applications by filtering resumes based on predefined keywords, skills, job titles, and other criteria. This assists recruiters in efficiently identifying qualified candidates for open positions.

  • Use simple formatting: ATS systems best read resumes with clear and straightforward formatting. Avoid using headers or footers, tables, images, or graphics, as these can confuse the ATS.
  • Include relevant keywords: Tailor your resume with keywords from the job description. ATS systems scan for these keywords to determine if your skills and experiences match the job requirements.
  • Stick to standard headings: Use common heading titles like “Work Experience,” “Education,” and “Skills” to ensure the ATS can easily find and categorize your information.
  • Choose the correct file type: Submit your resume as a Word document (.doc or .docx) or a plain text file (.txt) for maximum compatibility. Avoid PDFs unless specified.
  • Keep consistent job titles: If your previous job titles are not industry-standard, consider altering them slightly (without misrepresenting your role) to match more familiar titles.
  • Avoid fancy fonts or creative layouts: Stick to traditional fonts like Arial, Calibri, or Times New Roman. Creative designs and fonts might look appealing but can be problematic for ATS parsing.
  • Use full forms and acronyms: If you include technical terms or certifications, use their spelled-out form and acronyms to ensure the ATS recognizes them.
  • Be precise with dates: Format dates clearly and consistently, ideally in a ‘Month YYYY’ format.
  • Proofread for spelling and grammar: Errors can confuse the ATS. Proofread your resume or use a tool to check for accuracy.
  • Test your resume: Before submitting, test it through an ATS resume checker to see how it reads your information.

By following these guidelines, your resume will be better equipped to pass through ATS filters, increasing your chances of landing an interview.
