Hard Skills
Specific, teachable, and measurable abilities — technical tools, software, languages, certifications, and domain knowledge. Hard skills are what you learned; soft skills are how you work. ATS systems primarily filter on hard skills.
Hard skills are concrete, verifiable competencies that you can learn through education, training, and practice. They're the specific tools and knowledge you bring to a job. **Examples by field:** - Engineering: Python, JavaScript, AWS, Kubernetes, SQL - Finance: GAAP, financial modeling, Excel, Bloomberg Terminal, DCF analysis - Marketing: Google Analytics, HubSpot, Salesforce, SEO, A/B testing, copywriting - Design: Figma, Adobe Illustrator, Sketch, Prototyping, User Research - Healthcare: ICD-10 coding, phlebotomy, EMR systems, HIPAA compliance **Why hard skills dominate ATS:** ATS systems are built to match specific terms. 'Python,' 'Salesforce,' and 'CPA' are highly searchable. 'Strong communicator' is not. **Skill levels:** Consider noting proficiency for skills where level matters significantly: 'Spanish (Conversational),' 'Python (Advanced),' 'Figma (Expert).' For most tools, just listing them is sufficient unless a role specifically requires a high-level user. **Keeping skills current:** Listing skills from 5+ years ago that you haven't practiced since can create interview problems. Hiring managers may ask you to demonstrate skills listed on your resume. Only list hard skills you could actually perform today.
Why it matters
Hard skills are the gatekeeping mechanism in most ATS systems and the primary qualifier in technical screening. A candidate with a weaker soft skill presentation but strong technical depth will typically advance further than the reverse in most industries.
Candidate tip
Audit your skills section against the last 5 job descriptions you've saved — any skill mentioned in more than one that isn't on your resume should be added immediately if you have it.

Soft Skills
