Prepare 2-3 STAR stories for each of these themes. They show up consistently in senior Administrative Assistant loops.

1. 1System and process design at scale
2. 2Mentoring case studies
3. 3Driving alignment across teams
4. 4Trade-off analysis on roadmap calls
5. 5Leadership through ambiguity

1. Match the level of scope: Show leverage. Most bullets should describe how your work influenced other people's output, not just your own.
2. Use senior-appropriate verbs: Led, Architected, Drove, Spearheaded, Scaled, Mentored. Avoid generic verbs like "helped" and "worked on" — they read as low-ownership.
3. Quantify outcomes: Numbers, percentages, and dollars beat adjectives. "Reduced churn 22%" is more persuasive than "significantly improved retention".
4. Match Microsoft Office, Calendar Management, Data Entry keywords: These are the ATS-critical terms for Administrative Assistant roles. Make sure they appear in both your skills section and at least one bullet point.
5. Tailor to the job description: Run your final resume through the ATS checker against the specific JD. Aim for 70%+ keyword match before submitting.
