4 Common Systems Administrator Resume Mistakes
Listing generic duties instead of quantified Systems Administrator achievements — ATS and recruiters both reward numbers.
Omitting exact keywords like Linux/Windows Server, Active Directory/LDAP, VMware/Hyper-V, so the resume never clears keyword-matching filters.
Using multi-column layouts, tables, or graphics that ATS parsers garble into unreadable text.
Writing one generic resume for every application instead of tailoring the summary and skills to each Systems Administrator posting.
