Studies of recruiter behavior consistently show that the average initial resume review lasts 6 to 10 seconds. Eye-tracking research from TheLadders found that recruiters spend most of that time on your name, current title, current company, previous title, previous company, and education. Everything else is secondary until you pass the initial filter.

Resume Format: Which One to Use

Format	Structure	Best For	Avoid When
Chronological	Work history in reverse date order	Consistent career progression in one field	Career gaps or pivots
Functional	Skills-first, minimal employment history	Career changers with skill gaps in dates	Most corporate hiring (ATS unfriendly)
Combination/Hybrid	Skills summary + reverse-chronological history	Career changers with strong transferable skills	Entry-level roles (over-engineered)

For most job seekers, the reverse-chronological format is the safest choice. It is what recruiters and ATS systems expect.

The Seven Sections of an Effective Resume

1. Header

Your name (large, visible), phone number, professional email, LinkedIn URL, and location (city and state or country only, no street address). If you have a portfolio or GitHub, include it here. No photo unless applying in a country where photos are standard.

2. Professional Summary (Optional but Powerful)

Two to three sentences that immediately tell a recruiter who you are, what you do best, and what you are looking for. Write it last, after you have the rest of the resume. Example: “Operations manager with 8 years in logistics, specializing in supply chain optimization for mid-market consumer goods companies. Led cross-functional teams that reduced fulfillment costs by 18% over two years. Seeking director-level role in high-growth operations.”

3. Work Experience (Reverse Chronological)

Company name, job title, employment dates (month/year), and 3 to 5 bullet points per role. Each bullet should follow the format: action verb + what you did + measurable result. Use past tense for previous roles, present tense for your current role.

Weak: Responsible for managing customer accounts
Strong: Managed 47 enterprise accounts totaling $8.2M ARR, achieving 94% renewal rate and growing average contract value by 22% year-over-year

4. Skills Section

List hard skills (software, tools, languages, certifications) relevant to the role. Do not list soft skills (leadership, communication) here; demonstrate them through your experience bullets. Mirror the language used in the job posting for ATS compatibility.

5. Education

Degree, major, institution, graduation year. If you graduated more than 10 years ago, GPA is unnecessary. Relevant coursework, honors, and activities are optional but can help entry-level candidates with limited experience.

6. Certifications (If Relevant)

List certifications with the issuing organization and date. Prioritize certifications that appear in job postings for your target roles. Expired certifications can be listed if they remain relevant and are labeled with the completion date.

7. Optional Sections

Volunteer work (especially relevant for career changers), publications, speaking engagements, patents, or languages. Include only if directly relevant to the role or if you need to fill out a thin resume.

ATS Optimization: Getting Past the Robots

Most large employers use Applicant Tracking Systems to filter resumes before a human sees them. Common ATS systems include Workday, Greenhouse, Lever, and iCIMS. To pass:

• Use a clean, single-column format with standard section headers (not “Where I Have Been” instead of “Experience”)
• Include exact keywords from the job description, especially job titles, required tools, and skills
• Avoid headers and footers, text boxes, tables in your experience section, and images (all can confuse ATS parsers)
• Use .docx or PDF format; .docx is safer for ATS, PDF is better for humans. When in doubt, submit both or ask which is preferred.
