Resume keywords & skills for a Systems Administrator
For a systems administrator resume, the keywords recruiters and parsers scan for fall into three buckets: core technical skills (Linux and Windows Server administration, Active Directory, backup and recovery, patch management, virtualization, networking), a concrete toolset (Bash / PowerShell, VMware, Hyper-V, Ansible, Nagios / Zabbix, Group Policy, TCP/IP), and human skills like troubleshooting and documentation. Paste your resume below to see which of this role's keywords you hit and which you're missing — comparison only, nothing uploaded. One honest note: adding keywords makes your resume more relevant to the role; it isn't a trick to fool the machine.

Keywords are relevance, not a trick
Sysadmins are trusted with other people's servers and data, so hiring teams want proof you can carry the load — list only systems and tools you've actually run. 'I never really touched that' during an outage costs far more than a gap on paper.
Frequently asked questions
Start with what you genuinely run day to day. A Linux shop wants Bash scripting, service deployment, monitoring and alerting; a Windows domain wants Active Directory, Group Policy, patch management. Then add backup/recovery and troubleshooting, which nearly every posting expects. Instead of a long noun pile, show how many machines you managed, the uptime you held, and an outage you resolved.
Don't pad it. Mixed environments are common, but most roles lean one way — read the JD's main battlefield first. If the role truly is mixed and you only cover half, state your strength honestly and mark the other half 'familiar / learning.' Faking domain-controller experience falls apart the moment an interviewer asks how you'd troubleshoot it.
Follow the words the JD repeats. Ops/platform roles surface virtualization, automation (Ansible), monitoring and backups; network-leaning roles surface TCP/IP, DNS/DHCP, VPN and firewalls. Tilt your resume toward the target role's frequent terms — but only the parts you've actually done. Don't invent routing configs to match a networking JD.
No, and no tool can. Many sysadmin roles add a hands-on or troubleshooting interview, so keywords only earn you the relevance to get there. What decides the outcome is the real scenarios you've handled. PolishCat helps you see the gap; it doesn't sell a 'guaranteed pass' myth.
