How to Write a Resume in 2025: Complete Step-by-Step Guide

Writing a resume that gets past ATS filters and impresses hiring managers takes more than listing your jobs. This guide walks you through every section, every decision, and every formatting choice - with examples.

Why your resume matters in hiring

Your resume is the first filter in the hiring process. Recruiters and ATS systems decide in seconds whether to move you forward. The numbers below show why investing in a strong, ATS-friendly resume pays off.

Fact Impact
Time recruiters spend on initial resume scan6–7 seconds on average (eye-tracking studies)
Resumes rejected by ATS before a human sees them~75%
Applicants who get an interview (per role)~2% (about 4–6 people per 250 applications)
Fortune 500 companies using ATS98.8%
Rejection rate for typos or grammar errors77%
Rejection rate for wrong file format (e.g. image files)43% (auto-rejected by ATS)
Callback increase with quantified achievements~40% more callbacks
Interview chance with a tailored resume~61% more likely to get an interview
Recruiters who prefer one page (under 10 years experience)73%

Bottom line: a clear, keyword-matched, error-free resume gets past ATS and earns a longer look from recruiters. Score your CV with CVfive to see how you compare.

Choose the right resume format

The three main resume formats are chronological, functional, and combination. For most job seekers, reverse-chronological is the safest choice — it's what recruiters expect and what ATS systems parse most reliably.

Recommended

Reverse-chronological

Most recent job first. Best for consistent work history. ATS handles this format best.

Functional

Skills over job history. Use only for large employment gaps or career changes.

Combination

Skills summary + chronological history. Good for career changers.

Write a strong resume summary

Your resume summary is the first thing a recruiter reads. It should be 2–3 sentences that answer: who you are, what you bring, and what you're targeting.

What to include

Use your current or target job title, one or two key achievements (with numbers if possible), and the type of role you're seeking. Avoid generic phrases like “hardworking team player.”

Summary vs. objective

Use a summary when you have experience: it sells your value. Use an objective only for entry-level or career-change situations where you need to state your goal in one sentence.

✗ Weak

Hardworking professional with great communication skills seeking a challenging role where I can grow.

✓ Strong

Product Manager with 5 years building B2B SaaS products. Led a team that shipped 3 major features increasing ARR by 40%. Seeking PM roles at growth-stage startups.

Quantify your experience bullets

Every bullet in your work experience section should follow: Action verb + what you did + measurable result. Numbers grab attention and prove impact.

Strong action verbs to use

Start bullets with verbs like:

Led Launched Grew Reduced Improved Managed Developed Implemented Increased Streamlined

If you don't have exact numbers, use ranges or percentages (e.g. “reduced processing time by approximately 30%”).

✗ Weak

Managed social media accounts and helped with marketing.

✓ Strong

Grew Instagram following from 2K to 28K in 8 months by implementing a content calendar and daily engagement strategy.

Optimize for ATS (Applicant Tracking Systems)

Over 90% of large companies use ATS software to filter resumes before a human reads them. To pass ATS:

Standard section headings
Work Experience, Education, Skills
Simple layout
Single column, no tables or graphics
Match job keywords
Use terms from the posting naturally
PDF or DOCX
Avoid JPG/PNG — ATS can’t parse them

Submit PDF or DOCX. CVfive’s ATS checker scores your resume against these criteria.

Format and length guidelines

Length and readability directly affect whether your resume gets read.

📄
Length
1 page under 10 years · 2 pages for senior · Never 3 pages
🔤
Font & Layout
10–12pt · Arial/Calibri/Georgia · 0.5–1in margins
🚫
Avoid
Photos · decorative graphics · fancy columns · tables

Tailor every application

A generic resume rarely works. For each application, spend about 5 minutes:

  1. Read the job description carefully.
  2. Identify 3–5 keywords or phrases they repeat.
  3. Mirror those keywords in your summary and bullets.
  4. Reorder bullets so the most relevant experience appears first.

This targeted approach consistently outperforms sending the same resume everywhere. Tailored resumes are ~61% more likely to lead to an interview.

Common resume mistakes to avoid

⚠️
Generic language

Phrases like “hardworking team player” add no value. Replace with specific achievements and numbers.

⚠️
No numbers

Bullets that don’t quantify impact get skipped. Add scale, time, or percentage where you can.

⚠️
Wrong length

Too long (e.g. 3 pages for 5 years) or too dense. One page for early-career; two only when needed.

⚠️
Spelling and grammar errors

77% of recruiters reject resumes with typos. Proofread and use a second pair of eyes or a tool.

⚠️
Wrong file type

Sending JPG/PNG or obscure formats. Use PDF or DOCX so ATS can parse your resume.

⚠️
Photo (in the US/UK/Canada)

Including a photo can trigger instant rejection in many markets. Omit unless the country norm expects it.

Frequently Asked Questions

How long should a resume be?

One page for under 10 years of experience, two pages for senior roles. Never three pages unless you're a senior academic or executive.

Should I include a photo on my resume?

In the US, UK, and Canada: no. In some European and Asian countries: yes. Check local norms for your target market.

What's the difference between a resume and a CV?

In the US, 'resume' is a 1-2 page document for job applications. A 'CV' (curriculum vitae) is a longer academic document. In Europe and many other regions, CV and resume are used interchangeably.

How do I write a resume with no experience?

Lead with education, then add internships, volunteer work, personal projects, and relevant coursework. Focus on transferable skills and any quantifiable results, even from school projects.

What file format should I use for my resume?

Use PDF or DOCX. Avoid image formats (JPG, PNG) — many ATS systems cannot parse them and will reject your resume.

Should I use a resume template?

Yes. A clean, single-column template improves ATS compatibility and readability. Choose one that uses standard section headings and avoids tables or graphics.

How do I explain employment gaps on my resume?

Use a functional or combination format to lead with skills. Briefly note the gap in a cover letter if relevant (e.g. caregiving, study). Focus on recent achievements and continuous learning.

When should I use a resume summary vs. an objective?

Use a summary when you have experience: it highlights your value in 2-3 sentences. Use an objective only for entry-level or career-change roles where you need to state your goal in one sentence.
