What is Resume? Definition, Sections, Formats, Writing Steps, Skills, Templates

A resume is the single most important document in your job search. It is the first thing a recruiter sees, the first filter you have to pass, and in most cases, the only chance you get to make an impression before someone decides whether to call you.

But writing a strong resume is not just about listing your jobs and education. It is about understanding what hiring managers look for, how ATS systems scan and filter applications, which format presents your background most effectively, and how to turn your experience into a compelling case for why you are the right person for the role.

This guide covers everything you need to know. You will learn what a resume actually is and how it differs from a CV. You will understand what ATS-friendly means and why it matters in a job market where 97.8% of Fortune 500 companies use automated screening software. You will know exactly which sections to include, what properties each section requires, and how to write achievement-based content that gets results.

The guide also walks you through all three resume formats, explains which skills belong on your resume and how to categorize them, and gives you an 11-step writing process that takes you from a blank page to a polished, tailored document ready to send.

Whether you are writing your first resume, returning to the job market after a gap, or refining a document you have used for years, this guide gives you the knowledge and the tools to do it right. Zenvy CV puts all of it into practice so you can build, tailor, and export a professional resume in one place.

What is a Resume?

A resume is a one-to-two page document that summarizes your work experience, education, and skills for a potential employer. Its purpose is simple: to get you an interview.

A strong resume answers three questions for the hiring manager: Who are you? What have you done? Why should we call you?

The competition is real. There are around 250 applicants for every corporate job posting, and only 2 to 3% of sent resumes actually result in an interview. Your resume is the first filter, and in most cases, it is the only chance you get.

What is an ATS-Friendly Resume?

ATS stands for Applicant Tracking System. Most companies use ATS software to automatically scan and filter resumes before a human ever reads them. In 2025, 97.8% of Fortune 500 companies use a detectable ATS. If you are applying to a large company, your resume will almost certainly be processed by one before any human sees it.

A staggering 75% of resumes never reach human eyes because they fail to pass ATS keyword checks. An ATS-friendly resume uses standard formatting, recognizable section headings, and relevant keywords so the software can parse it correctly. Fancy tables, graphics, and unusual fonts often break ATS parsing and get your resume rejected before anyone sees it.

Key rules for ATS compatibility:

• Use standard fonts like Inter or Roboto for modern roles, or Merriweather and Lora for classic and elegant styles
• Avoid text boxes, columns, and embedded images
• Use clear headings like "Work Experience" and "Education"
• Mirror keywords from the job description naturally throughout your content

Zenvy CV handles all of this automatically. Every template in Zenvy CV is built to pass ATS parsing cleanly, so you never have to worry about formatting breaking your application behind the scenes.

What Is the Difference Between a CV and a Resume?

A resume is short, tailored, and used primarily for job applications in the US, Canada, and Australia. A CV (curriculum vitae) is a comprehensive academic record used in Europe, academia, and research fields with no strict page limit.

If you are applying for a corporate job, you need a resume. If you are applying for a university position, fellowship, or research role, you likely need a CV. Zenvy CV supports both formats, so you can build the right document for the right opportunity.

What Should You Include in a Resume?

A resume has required sections that every hiring manager expects to see, and optional sections you add only when they strengthen your case. Getting this structure right is the foundation of a resume that reads clearly and gets results.

Contact Information

Contact Information is always first. Include your full name, professional email, phone number, LinkedIn profile URL, and portfolio link if relevant. Your street address is optional in modern resumes. In 2024, 33% of resumes were still missing a LinkedIn profile in the resume summary. Do not be part of that statistic.

Professional Summary

Professional Summary sits directly below your contact information. It is a 2-to-3 sentence snapshot of your experience, top skills, and what you bring to the role. Write it last, after the rest of your resume is complete.

Work Experience

Work Experience is the most important section. List jobs in reverse chronological order, with your most recent position first. For each role, include the job title, company name, location, and dates of employment. Use bullet points to describe your achievements, not just your duties. Lead each bullet with a strong action verb and include numbers wherever possible.

Resumes that include hard metrics can have as much as a 40% higher chance of earning an interview. Despite this, only 8% of resumes use numerical data. That gap is your advantage.

Skills

The Skills section lists your core competencies. Group them logically: technical skills, tools, languages, and soft skills. Only list skills you can confidently discuss in an interview. More than 40% of recruiters say that applicants lack the necessary soft skills for the job, so do not skip this section or treat it as an afterthought.

Education

Education lists your highest degree first. Include the degree name, institution, graduation year, and GPA only if it is above 3.5 or if you are a recent graduate.

Optional Sections

Add these only when they strengthen your application.

• Certifications are worth including when they are directly relevant to the role. Include the certification name, issuing organization, and the year earned.
• Projects are especially valuable for students, career changers, and developers. Briefly describe what the project was, what technologies or methods you used, and what the outcome was.
• Languages should include your proficiency level. Use recognized standards like Native, Fluent, Conversational, or Basic.

Zenvy CV includes all of these sections as ready-to-fill blocks. You simply choose which sections to include, drag to reorder them, and fill in your details.

What are the Three Types of Resume Format?

The three types of resume format are listed below:

Chronological Resume

Chronological resume lists work experience from most recent to oldest. It is the most widely used and accepted format. Recruiters prefer it because it makes your career progression easy to follow.

Functional Resume

A functional resume focuses on skills rather than a timeline of jobs. It is often used by people with employment gaps or those changing careers entirely. However, many recruiters and ATS systems distrust it, so use it carefully.

Combination Resume

Combination resume (also called a hybrid) leads with a skills summary followed by a chronological work history. It works well for experienced professionals making a lateral move or transitioning into a new industry.

What is the Best Resume Format?

For most job seekers, the chronological format is the safest and most effective choice. Recruiters are familiar with it, ATS systems process it cleanly, and it tells a clear professional story.

Use a functional or combination format only if your situation genuinely calls for it, not just to hide gaps. A gap is better addressed with a brief honest note than by obscuring your timeline.

Zenvy CV offers all three formats as selectable layouts. You can switch between them without losing your content, so you can test which one presents your background most effectively before you download.

How To Write a Professional Resume?

Writing a professional resume is not about listing every job you have ever had. It is about presenting your experience, skills, and value in a way that makes a recruiter stop and say "let's call this person." Here is exactly how to do that, step by step.

Step 1: Research the Role Before You Write Anything

Most people open a blank document and start typing. That is the wrong approach.

Before you write a single word, read the job description carefully from top to bottom. Identify the exact skills the employer is asking for, the qualifications they require, and the language they use to describe the role. Note repeated words and phrases because those are your keywords.

Ask yourself three questions:

• What does this employer actually need?
• Which parts of my background directly match that need?
• What proof do I have that I can deliver results in this area?

Your answers shape everything else on the resume. A resume written without this research is generic by default, and generic resumes get ignored. 83% of recruiters confirm they are more likely to hire candidates who tailored their resume to the specific job.

Zenvy CV lets you save the job description alongside your resume draft so your keywords and content stay aligned as you write.

Step 2: Choose the Right Resume Format

There are three formats to choose from, and picking the wrong one can work against you even if your experience is strong.

• Chronological format lists your work history from most recent to oldest. This is the most widely accepted format and the one recruiters expect to see. Use it if you have a consistent work history in the same field.
• Functional format leads with skills rather than job history. It is sometimes used by career changers or people with employment gaps. However, many ATS systems struggle to parse it and many recruiters distrust it. Use it only when your situation genuinely calls for it.
• Combination format opens with a skills summary and follows with a chronological work history. It works well if you are switching industries but still have relevant experience to show.

When in doubt, choose chronological. It is clean, familiar, and ATS-safe. Zenvy CV lets you switch between all three formats without losing any of your content, so you can test each one and see which presents your background best.

Step 3: Set Up Your Contact Information

Your contact section should be the very first thing at the top of the page. Keep it clean and complete.

Include:

• Full name (larger font, visually prominent)
• Professional email address
• Phone number
• LinkedIn profile URL
• Portfolio or personal website link if relevant to the role
• City and country (full street address is optional)

A few things to avoid: unprofessional email addresses, phone numbers without a country code if you are applying internationally, and LinkedIn URLs you have never customized. In 2024, 33% of resumes were still missing a LinkedIn URL entirely. That is a missed opportunity every time.

Step 4: Write Your Work Experience Section

This is the most important section on your resume. Recruiters go here first.

List each role in reverse chronological order. For each position include the job title, company name, location, and the dates you worked there using a consistent format such as "Jan 2021 to Mar 2024."

Write achievement bullets, not duty lists.

Most resumes describe what a person was responsible for. Strong resumes describe what a person actually accomplished. There is a significant difference.

Duty-based bullet: "Responsible for managing social media accounts." Achievement-based bullet: "Grew Instagram following from 4,200 to 31,000 in 8 months by launching a weekly video series."

Use this simple formula for every bullet point:
Action verb + task or project + measurable result

Strong action verbs to use: led, built, launched, reduced, increased, managed, designed, negotiated, streamlined, generated, cut, delivered, scaled, trained, secured.

Aim for 3 to 5 bullets per role. Senior or more relevant roles can have up to 6. Older or less relevant roles can have 2 to 3. Resumes that include hard metrics have up to a 40% higher chance of earning an interview, yet only 8% of resumes actually use numerical data. Use numbers wherever you can: percentages, revenue figures, team sizes, timeframes, and volume.

Step 5: Build a Strong Skills Section

Your skills section tells a recruiter at a glance whether you have the tools the role requires.

Organize your skills into clear groups:

• Technical skills are hard, measurable abilities specific to your field. Examples include Python, SQL, AutoCAD, financial modeling, and Adobe Illustrator.
• Soft skills are behavioral and interpersonal traits. Examples include leadership, communication, stakeholder management, and conflict resolution. Do not just list them as standalone words. Back them up with evidence in your experience bullets instead.
• Industry skills are domain-specific competencies that signal you understand the field. A digital marketer might list SEO, conversion rate optimization, and paid social. A logistics professional might list supply chain management, demand forecasting, and vendor negotiation.
• Tools and technologies are the platforms and software you use day-to-day. Examples include Salesforce, HubSpot, Jira, Figma, Google Analytics, and Microsoft Excel.

64.8% of employers now use skills-based hiring practices, which means your skills section is being evaluated more critically than ever. Only list skills you can genuinely discuss in an interview. Inflating your skills is one of the fastest ways to lose an offer at the interview stage.

Step 6: Write Your Education Section

For most professionals, education is a short section. List your highest degree first.

Include for each qualification:

• Degree name and field of study
• Institution name
• Graduation year
• GPA only if it is 3.5 or above, or if you are a recent graduate

If you are a recent graduate with limited work experience, move education above your work experience section. Add relevant coursework, academic projects, or thesis topics if they strengthen your application for the specific role.

If you graduated more than 10 years ago and have solid work experience, keep education brief. A single line per degree is enough.

Step 7: Add Optional Sections That Strengthen Your Case

Optional sections should only appear on your resume if they add genuine value for the specific role you are applying for. Adding them for the sake of filling space weakens the document.

• Certifications signal continuous learning and role-specific expertise. Include the certification name, the issuing organization, and the year you earned it. Examples include Google Analytics Certification, PMP, AWS Solutions Architect, and CFA Level 1.
• Projects are valuable for developers, designers, students, and career changers. For each project include a one-line description of what it was, the tools or methods you used, and the outcome or impact. Keep each entry to two or three lines.
• Languages can be a significant differentiator in certain roles and industries. Always include your proficiency level: Native, Fluent, Conversational, or Basic.
• Volunteer work is worth including if it demonstrates skills or leadership relevant to the role, especially for candidates early in their careers.

Step 8: Write Your Professional Summary Last

Most people write their summary first. Write it last instead, once every other section is complete and you can see the full picture of what you have built.

A strong professional summary is 2 to 3 sentences. It should answer three things: who you are professionally, what you are best at, and what you bring to this specific role.

Weak summary: "Hardworking professional with experience in marketing seeking a new opportunity."

Strong summary: "Digital marketing manager with 6 years of experience scaling paid acquisition for B2B SaaS companies. Managed over $2M in annual ad spend across Google and Meta, consistently delivering 30% below target CPA. Looking to bring performance-driven strategy to a high-growth product team."

The strong version is specific, quantified, and tailored. The weak version could belong to anyone. Zenvy CV's summary prompt guides you through writing this section with the right structure so you do not start from a blank page.

Step 9: Tailor the Resume for Every Application

A single master resume sent to every job is one of the most common and costly mistakes job seekers make. Candidates who tailor their application to each role get a 78% higher response rate than those who send a generic version.

Tailoring does not mean rewriting the entire document each time. It means:

• Adjusting your professional summary to reflect the specific role
• Reordering or rewording skills to match the job description keywords
• Moving the most relevant experience bullets to the top of each role
• Aligning your job title in the summary with the title being advertised where honest and appropriate

Zenvy CV lets you duplicate your base resume in one click and edit the copy for each application, keeping your tailored versions organized and easy to find.

Step 10: Format for Readability and ATS Compatibility

Once the content is written, formatting is what determines whether a human and a machine can both read it easily.

Follow these rules:

• Font: Use Inter or Roboto for a modern look. Use Merriweather or Lora for a classic or elegant tone. Keep body text between 10pt and 12pt. Never go below 10pt.
• Layout: Use a clean single-column or simple two-column layout that does not rely on tables or text boxes. Avoid sidebars, graphics, and icons as structural elements.
• White space: Leave enough margin and spacing between sections so the page does not feel crowded. Recruiters skim, and white space helps them find what they are looking for faster.
• Section headers: Use clear, standard labels. "Work Experience" not "My Journey." "Education" not "Where I Studied." ATS systems look for recognized headers.
• File format: Save and submit as a PDF unless the job posting specifically requests a Word document. PDF preserves your formatting across devices.
• Length: One page for under 10 years of experience. Two pages maximum for senior roles. Never three pages unless you are in academia or research.

All Zenvy CV templates are pre-built to these exact standards. Every font, margin, spacing, and layout choice has been tested for both recruiter readability and ATS compatibility, so you export with confidence.

Step 11: Proofread Until It Is Perfect

A single typo can cost you an interview. Recruiters notice errors immediately and many use them as a reason to disqualify a candidate, especially for roles that require attention to detail, writing, or communication.

How to proofread effectively:

• Read the entire resume out loud. Your ear catches errors and your eye skips.
• Read it backwards, sentence by sentence, to isolate each line from context.
• Use a spell checker, but do not rely on it alone. Spell checkers miss correctly spelled but wrongly used words.
• Check every date for consistency and accuracy.
• Ask a second person to review it. Fresh eyes catch things you are blind to after hours of editing.
• Print it out if possible. Errors that hide on screen often appear on paper.

Once you are satisfied, export a clean PDF from Zenvy CV and save a copy. Your resume is ready.

Which Skills Should You Put on a Resume?

Skills on a resume fall into four categories.

Technical Skills:

Technical skills are specific, measurable abilities tied to a field. Examples include Python, financial modeling, Adobe Photoshop, and data analysis.

Soft skills:

Soft skills are interpersonal and behavioral traits. Examples include communication, leadership, problem-solving, and time management. Do not just list them as words. Demonstrate them through your experience bullets instead.

Industry skills:

Industry skills are domain-specific competencies. A marketer might list SEO, paid media, and content strategy. A nurse might list patient triage, EHR systems, and medication administration.

Tools and Technologies:

Tools and technologies include software, platforms, and systems you use. Examples include Salesforce, Figma, Jira, Google Analytics, and Microsoft Excel.

Only include skills that are relevant to the role and that you can back up in an interview. 64.8% of employers are now using skills-based hiring practices, so a well-built skills section carries more weight today than it did even a few years ago.

How Long Should a Resume Be?

For most professionals with under 10 years of experience, one page is the standard. For senior professionals, executives, or those with extensive publication or project lists, two pages is acceptable. Recruiters are 2.9 times more likely to choose a two-page resume for managerial positions, and 1.4 times more likely for entry-level positions.

A simple rule: every line on your resume should earn its place. If removing something does not weaken your case, remove it. Zenvy CV shows you a live page preview as you write, so you always know exactly how much space you are using.

How Do You Write a Resume With No Experience?

Focus on what you do have. Relevant coursework, academic projects, volunteer work, internships, part-time jobs, and extracurricular leadership all count.

Structure your resume with education at the top, followed by projects or volunteer experience, then skills. Use your professional summary to frame your potential and enthusiasm rather than apologize for a short history.

A targeted skills section and two or three strong project descriptions can make a no-experience resume genuinely competitive. Zenvy CV includes a dedicated student and entry-level template designed specifically for this situation, with section prompts that guide you on what to write.

What Makes a Good Resume Template?

A good template is clean, readable, and ATS-compatible. Resumes that succeed in capturing recruiter attention feature simple layouts with clear sections and heading titles. Resumes with cluttered layouts, a lack of white space, multiple columns, and long sentences perform significantly worse.

Choose a font that matches the tone of your industry. Inter and Roboto work well for tech, business, and corporate roles. Merriweather and Lora suit law, academia, finance, and creative fields where a more refined look is expected.

Avoid templates with profile photos, colorful sidebars, and decorative icons unless you are in a creative field where design itself is part of the job. A striking 88% of resumes are rejected due to including a photo, so keep it clean and professional by default.

All Zenvy CV templates are designed with these principles built in. You pick the style, choose your font, and the layout handles everything else. The best template is one that stays out of the way and lets your content do the work.

Resume Examples

Resume examples serve as practical references, not templates to copy word-for-word. Looking at examples in your specific field helps you understand what hiring managers in that industry expect to see.

Useful resume examples to look for:

• Entry-level resume with no experience
• Software engineer resume
• Marketing professional resume
• Career change resume
• Executive or senior leadership resume
• Student or recent graduate resume

When reviewing examples, pay attention to how achievements are phrased, how sections are ordered, and how much detail each role includes at different career levels. Zenvy CV includes a built-in example library across all major industries and experience levels, so you can reference real samples directly inside the builder while you write.

FAQs About Resume

Should a resume be one page?

For most people with fewer than 10 years of experience, yes. Quality always beats quantity. A tight one-page resume reads better than a padded two-page one. Zenvy CV's live page preview makes it easy to trim your content to fit cleanly on one page without guessing.

What font should I use?

Use clean, professional fonts. Zenvy CV offers four curated options: Inter for a modern look, Roboto for a clean and neutral style, Merriweather for a classic feel, and Lora for an elegant, editorial tone. All four are ATS-safe and professionally tested.

Can I use colors in my resume?

A single subtle accent color used sparingly is generally acceptable. Avoid multiple colors, bright shades, or color as a structural element, since ATS systems may not render it correctly. Zenvy CV's color system uses professionally tested accent palettes so you stay within safe, recruiter-approved limits.

Are resume templates ATS-friendly?

Not all of them. Templates from word processors like Microsoft Word are usually safe. Templates built with heavy design tools, multiple columns, or graphics-heavy layouts often fail ATS parsing. Zenvy CV templates are built with ATS compatibility in mind, so every template passes parsing cleanly without sacrificing design quality.

Should I include hobbies?

Only if they are genuinely relevant to the role or reveal a meaningful quality. A software developer listing open-source contributions adds value. Listing "watching Netflix" does not.

How often should I update my resume?

Update it every time you complete a significant project, earn a promotion, gain a new skill, or change jobs. Do not wait until you are job hunting to start from scratch. Around 10% of job seekers have applied for 50 or more jobs without hearing back. A well-maintained, up-to-date resume dramatically reduces the chances of falling into that group. Keeping your Zenvy CV account updated means your resume is always ready to send, even when you are not actively looking.
