Every resume must pass two filters before getting you an interview: an ATS (Applicant Tracking System) and a human recruiter. These audiences have different preferences, and most people optimize for neither.
ATS (first filter): Software that scans resumes for keywords before a human sees them. Estimates suggest 75% of resumes are rejected by ATS before any human reads them. ATS systems look for exact keyword matches from the job description.
Recruiter (second filter): A human who spends an average of 7 seconds on initial resume review. They're looking for relevance, clarity, and evidence of impact.
ATS optimization essentials
- Use standard section headings: "Work Experience", "Education", "Skills" — not creative alternatives
- Include keywords verbatim from the job description
- Avoid tables, text boxes, headers/footers, and columns (ATS often can't parse these)
- Use standard fonts: Arial, Calibri, Georgia, Times New Roman
- Submit as .docx or simple PDF — never image-based PDFs
- Spell out acronyms at least once: "Search Engine Optimization (SEO)"
Resume format
For most job seekers, reverse chronological format is best — most recent experience first. This is what recruiters and ATS systems expect. Functional or skills-based resumes generally score poorly in ATS and should be avoided unless you're making a significant career change.
Writing strong work experience bullet points
The formula: Action verb + Task + Result
Weak: "Responsible for managing social media accounts"
Strong: "Grew Instagram following from 2,000 to 28,000 by implementing a content calendar and engagement strategy"
Weak: "Helped with customer support"
Strong: "Resolved 95% of customer tickets within 24 hours, improving satisfaction score from 3.2 to 4.7/5"
Strong action verbs by category
| Category | Verbs |
|---|---|
| Leadership | Led, Managed, Directed, Oversaw, Mentored |
| Achievement | Achieved, Exceeded, Surpassed, Delivered, Generated |
| Growth | Grew, Increased, Expanded, Scaled, Improved |
| Savings | Reduced, Cut, Saved, Eliminated, Streamlined |
| Creation | Built, Created, Developed, Launched, Designed |
What to include in each section
Professional summary
2–3 sentences at the top. Include: years of experience, key skills, and one notable achievement. Skip "References available upon request" — it's assumed.
Work experience
- Last 10 years of relevant experience (older roles can be shortened)
- 3–5 bullet points per role
- Include dates (month and year) and location
- Quantify results wherever possible
Skills section
List hard skills only — tools, technologies, languages, certifications. Soft skills like "good communicator" are meaningless without evidence. Place them in a scannable list, not a paragraph.
Education
Unless you're a recent graduate, keep this brief. List degree, institution, and year. GPA only if above 3.5 and within the last 5 years.
Resume length guidelines
| Experience level | Recommended length |
|---|---|
| 0–5 years | 1 page |
| 5–10 years | 1–2 pages |
| 10+ years | 2 pages maximum |
Tailoring your resume for each job
A generic resume performs poorly. The most effective approach is to:
- Read the job description carefully
- Note the specific keywords, tools, and requirements they list
- Mirror that language in your resume (verbatim where accurate)
- Reorder bullet points to lead with the most relevant experience
This takes 15–20 minutes per application but significantly increases callback rates.
