- Quantified achievement: Include at least one specific metric. Numbers grab attention and prove your impact.

Tips for Writing Your Systems Administrator Summary
- Keep it to 2-3 sentences (40-60 words). Hiring managers spend 6-7 seconds on initial resume scans, so every word needs to earn its place.
- Tailor your summary to each job application by mirroring keywords from the job description.
- Use a summary (not an objective) if you have 2+ years of experience. Objectives are better for career changers or new graduates.
- Avoid generic phrases like "hard-working" or "team player." Instead, demonstrate these qualities through specific achievements.
