Organize Your Skills Section
ATS-optimized keywords in the right order
Your skills section is heavily weighted by ATS systems. Organize skills by category and prioritize based on the job description. Include both hard skills and soft skills, but focus on technical competencies first.
Hard Skills / Technical
Tools & Technologies
Soft Skills
Certifications
Pro Tip: Match Job Descriptions
Before applying, scan the job posting for skill keywords. If they say "Python," don't write "programming"—use the exact term. ATS systems match literal strings.
Format Your Work Experience
Achievement-focused bullets with metrics
Each work experience entry should demonstrate increasing responsibility and impact. Use the STAR method (Situation, Task, Action, Result) for bullet points, always quantifying results when possible. Focus on achievements over responsibilities.
