ATS optimization tips
Spell out acronyms at least once
ATS software might not recognize 'AD' as 'Active Directory'. Write it as 'Active Directory (AD)' the first time you use it to ensure both terms are indexed.
Match the job description exactly
If the posting asks for 'Windows Server 2022', don't just write 'Windows Server'. Mirroring the exact phrasing helps you score higher in the ATS ranking.
Group technical skills by category
Create a dedicated 'Technical Skills' section categorized by Operating Systems, Networking, Virtualization, and Scripting to make it easily readable for both ATS and human recruiters.
