The 15-Second Scan a Recruiter Does on a Linux Engineer Resume
Hiring managers aren’t reading your resume; they’re scanning it for specific signals. They’re looking for evidence that you can solve complex problems, manage critical infrastructure, and communicate effectively with technical and non-technical stakeholders.

The Mistake That Quietly Kills Candidates
Listing skills without providing context or evidence is a common mistake that can sink your resume. Hiring managers want to see how you’ve used your skills to solve problems and achieve results. They want to see what you’ve actually *done*.
Use this when rewriting a resume bullet to emphasize impact.
Before: “Managed Linux servers.”
After: “Managed 50+ Linux servers in AWS, reducing infrastructure costs by 15% through automation with Ansible and improving system uptime to 99.99%.”
