Resume gap analysis for System Administrator

Linux administration depth is stated, never evidenced

Most System Administrator resumes list Linux administration as a bullet in a skills bar. Job descriptions ask what you built with it. Attach Linux administration to one project, its scope, and the result.

No numbers against server uptime

Hiring managers for this role scan for server uptime and patch compliance. A resume without those figures reads as a system administrator who was present, not one who moved anything.

VMware listed, Ansible missing

JDs for this role usually pair VMware with Ansible. Naming only one signals partial coverage of the workflow and drops your keyword match.

Windows Server and Active Directory buried under duties

Windows Server and Active Directory are core screening keywords for System Administrator openings, but they often sit at the bottom of a paragraph. An ATS weights the first lines of each role far more heavily.

Scope of ownership is unclear

"administer Linux and Windows server estates" means something different at a 5-person team and a 500-person org. State team size, budget, volume, or user count so the reviewer can place your Shell scripting experience.

Certifications and qualifications not surfaced

RHCSA, Microsoft Certified: Windows Server appear in the preferred section of most System Administrator JDs. If you hold one, it belongs near the top, not in a trailing "Others" line.
