Ensure your resume passes through automated screening systems
ATS-Friendly Formatting
- Use standard fonts (Arial, Calibri, Times New Roman)
- Include standard section headers (Experience, Education, Skills)
- Use bullet points instead of paragraphs
- Save as both .pdf and .docx formats
- Use simple, clean layouts without graphics
ATS Killers to Avoid
- Text in images or graphics
- Tables and complex formatting
- Fancy fonts and decorative elements
- Headers and footers with important info
- Unconventional section names
🎯 Authentic Keyword Strategy
Highlight your actual skills using language that matches the job posting:
- • Use exact technology names from job descriptions only for skills you actually possess
- • Include both abbreviations and full forms for your technologies (AI/Artificial Intelligence)
- • Use industry-standard terminology for your actual experience
- • Incorporate relevant soft skills you can genuinely demonstrate
⚠️ Important: Never add skills or technologies you don't actually know just to match keywords. This leads to poor job fit and interview failure. Focus on roles where your genuine skills align naturally.
