1. Matching keywords from the job posting: If they mention "Microsoft Excel" don't just write "spreadsheet software"
2. Using standard section headers: "Work Experience," "Skills," "Education" — avoid creative alternatives
3. Including specific software names: "QuickBooks Pro," "Microsoft Excel (Advanced — VLOOKUPs, Pivot Tables)"
4. Quantifying everything possible: Number of people supported, budget sizes, volume of tasks handled
5. Saving as .docx or PDF: Avoid unusual file formats that ATS may not parse correctly

• Ignoring the job description: Tailor your resume to each position by incorporating their specific requirements and language
• Outdated formatting: Use a clean, modern design. Avoid objectives statements — use a professional summary instead
• Missing technology skills: Administrative roles are increasingly tech-heavy. Always list your software proficiencies
