How to write a resume: a step-by-step guide with examples

How do you write a resume? Start with the role, not the template

Learning how to write a resume is mostly learning how to choose evidence. Before you open a template, read two or three real job postings for the work you want and identify the main duties, the essential qualifications, and the proof a hiring team could use to judge whether you are ready. Separate mandatory credentials, such as a license, from preferences.

A resume can make your relevant background easier to see; it cannot create a license or experience you do not have. Harvard’s career center describes a resume as a concise summary of your abilities, education and experience, and recommends tailoring it to the type of position you are seeking. That is the job of every step below.

Plan on an hour or two for a first full draft and far less for later versions. The steps are the same whether you are a student, a warehouse lead, a nurse or a software engineer; only the evidence changes.

1. Write a one-sentence target: the work you want to do and the evidence you already have for it.
2. Mark each requirement in the postings as met, partly met, or not yet supported.
3. Build a master record of your history (the next section).
4. Choose sections and an order that put your strongest relevant evidence first.
5. Write each experience entry and its bullets.
6. Add a summary and skills section only if they add information.
7. Tailor the selection and order to each specific posting.
8. Format for readability, export, and check the exact file you will send.

Collect your evidence in a master resume first

Keep a private master document that holds more than any single resume will: every employer, official title, start and end month, location, tool, project, training course and result you can support. Build each submitted resume from that record instead of rewriting your history from memory for every job.

Write rough notes, not polished bullets, at this stage. For each role, answer three questions: what was I responsible for, what did I change or produce, and how do I know it worked? Records such as performance reviews, old emails, project trackers and certificates help you recover accurate details and dates.

• Record promotions and title changes with their own dates.
• Note team size, volume, budget or customer counts only where you have a reliable source.
• Include volunteer work, contract work and projects; decide later whether each one belongs.
• Exclude confidential customer information and internal figures you are not allowed to disclose.

What should you put on a resume, and in what order?

Most U.S. resumes use a small set of standard headings: contact information, an optional summary, Experience, Education and Skills, plus Projects, Certifications or Volunteer Experience when they carry relevant evidence. Use plain heading names so both people and software can find each section.

Put the most relevant section first, then list entries within each section from most recent to oldest. Education usually leads for a current student or recent graduate; relevant experience usually leads for an established worker. A reverse-chronological layout suits most people, while a hybrid layout that opens with a short skills section can help a career changer. The resume format guide compares the options in detail.

Contact details belong in the main body of the page: your name, city and state, phone, a professional email address, and a portfolio or LinkedIn link if it adds evidence. A full street address, photo, date of birth, marital status and references are not expected on a U.S. resume and take space from evidence. Conventions differ in some countries and professions, so follow local norms and the application instructions.

How to write the experience section

Keep the employer, your official title, the location, and the start and end dates together on one or two lines, then place the bullets underneath. Month and year is the common date format; use the same format everywhere. Use present tense for a current job and past tense for completed work.

Keep official titles accurate. If a title is unusually broad or internal, add a truthful clarification in parentheses rather than replacing it with a more senior title, for example “Associate II (accounts payable)”. List promotions under one employer with distinct titles and dates so the progression is visible.

Most readers care about roughly the last 10 to 15 years of relevant work; the guide to how long a resume should be covers what to cut and what to keep. Older roles can be shortened to a title line or grouped under Earlier Experience when they add little, but do not change dates or hide a role an application form asks you to list. If you have a break in work history, a brief factual line such as “Family caregiving, 2022–2023” is usually enough.

• Contract or agency work: name the agency and the client if you are allowed, such as “Contract Analyst, Summit Staffing (assigned to Harbor Health)”.
• Several short gigs of the same kind: group them under one entry, such as “Freelance Bookkeeper, self-employed”.
• Three to six bullets for recent relevant jobs; one or two for older or less relevant ones.

How to write resume bullet points that show what you achieved

A useful bullet explains what you did, the scope or method, and why it mattered: action, context, result. Start with a precise verb rather than a self-rating such as “excellent communicator”; the resume action verbs guide has alternatives grouped by skill. Harvard’s guidance asks for language that is specific, active and fact-based.

Use numbers only when you can explain where they came from. When no outcome metric exists, describe scope (how many, how often, for whom), a deliverable, an adopted process or a verified quality improvement. Do not manufacture a percentage, and distinguish your contribution from a team result.

• Replace “helped with” by naming your actual contribution, not a more impressive but inaccurate verb.
• Put the bullets most relevant to the target near the top of each entry.
• Cut duties any reader would assume, such as “answered phones” for a receptionist, unless the posting stresses them.

Do you need a resume summary and a skills section?

A summary is optional. It earns its space when it tells the reader something the first job title does not: the role you are targeting, a transition, a specialty or a credential. Two or three lines is enough. Skip the old-style objective that says you want a challenging role; it describes your wishes, not your evidence. The resume summary examples show versions for different levels.

A skills section helps a reader scan for tools, systems, languages, licenses and methods. Keep it to items you can use now and would be comfortable being tested on, and group them if the list is long. Then prove the important ones in your bullets. Soft skills such as teamwork are more convincing shown in a bullet than listed; see how to choose skills for a resume.

Tailor each resume without changing the facts

Compare your draft with the specific posting before you apply. Move the most relevant achievements upward, rename a skill with the employer’s term when it accurately describes your experience, spell out an unfamiliar abbreviation, and remove low-value detail that hides your strongest evidence. The guide to tailoring a resume to a job description walks through a full before-and-after.

Tailoring changes selection and emphasis, never dates, titles, employers or seniority. Save each tailored version with the posting it was built for, so your interview answers match what you submitted.

A quick way to tailor is to rank your bullets against the posting’s top three requirements, then reorder so each requirement has evidence in the top half of the page. If a requirement has no evidence at all, leave the gap honest and address it in a cover letter or by building the skill.

Resume formatting and length: what actually matters

Choose a plain, readable layout: one column, standard fonts, body text around 10 to 12 points, consistent spacing and enough white space to scan. The University of Illinois career center warns that unusual fonts, layouts and graphics may not render properly, may be rejected by applicant tracking system scanners, and may not be read correctly by screen readers. Design effort is better spent on content.

Use the shortest length that keeps the evidence the role needs at a readable size. One page suits many students and early-career applicants; two pages is common with a longer relevant history. Do not shrink text or margins to force one page. Some settings have their own rules: U.S. federal job applications through USAJOBS now limit resumes to two pages, and academic CVs follow different conventions.

• Use real text for every word, not images or text boxes, so software can read it; see the ATS-friendly resume guide.
• Use bold for titles or headings consistently, not for random phrases.
• Name the file clearly, such as “Dana-Ortiz-Resume.pdf”, and use the file type the employer requests.

Proofread and test the exact file before you submit

Proofread the exported file, not only the editable draft. Open it on another screen size, check that links work, and copy its text into a plain-text editor to spot missing words or a confusing reading order. This is a readability check, not proof that every applicant tracking system will parse it correctly.

Read it once for errors and once as a hiring manager would: can you tell in a quick skim what role this person wants and which evidence supports it? Ask a friend, mentor or campus career adviser the same question. If the application form auto-fills from your resume, review and correct each field before submitting.

• Check phone, email, dates, spelling, page breaks and hyperlink destinations.
• Remove template instructions, tracked changes and accidental blank pages.
• Keep the submitted version with the job description for interview preparation.
