How Recruiters Screen a SysAdmin Resume
The 6-second scan criteria hiring managers and automated filters evaluate first:
- ✓Does the resume cover Linux/Windows server administration, active directory management, and virtualization (VMware, Hyper-V)?
- ✓Are backup/disaster recovery drills, automated patching, and security compliance audits documented?
- ✓Is there evidence of bash/PowerShell scripting to automate routine administration and resolve helpdesk escalations?
SysAdmin ATS Formatting & Parsing Guide
Avoid listing hardware specifications or vendor product numbers unless requested in the JD. Focus your bullets on server uptime percentages, fleet sizes managed, and routine task automation.
3 Common Mistakes to Avoid for SysAdmin Resumes
- ✕Listing routine manual tasks ("fixed printer and rebooted servers") rather than automated systems engineering.
- ✕Omitting server fleet sizes (e.g. 50+ VMs, 200+ servers, multi-datacenter).
- ✕Failing to mention backup verification and recovery time objectives (RTO/RPO).
