Common Questions
What is the standard resume length in the US for Principal Tech Systems Administrator?

What keywords should a Principal Tech Systems Administrator resume include for ATS?
Include role-specific terms from the job posting (e.g., tools, methodologies, certifications), standard section headings (Experience, Education, Skills), and industry buzzwords. Avoid graphics, tables, or unusual fonts that can break ATS parsing. Save as PDF or DOCX for maximum compatibility.

Use a brief, honest explanation (e.g., 'Career break for family' or 'Professional development') in your cover letter or a short summary line if needed. On the resume itself, focus on continuous skills and recent achievements; many US employers accept gaps when the rest of the profile is strong and ATS-friendly.
What is the ideal resume length for a Principal Tech Systems Administrator?
Ideally, your resume should be no more than two pages.
