To make a resume, gather everything you have done into one rough list, choose a simple one-column format, write a contact line and a three-sentence summary, list your experience newest first with result-shaped bullets, add education and skills, cut the page to one or two pages, then tailor it to the specific job posting before you send it. That is the whole process. The rest of this guide takes each step in turn, with the questions to ask yourself and the mistakes that cost interviews.

You can do every step below with a word processor and an hour of focus. Where a tool genuinely saves time, usually at the writing and tailoring stages, this guide says so and says when you do not need one.

Before you start: what a resume has to do

A resume has one job: get a person who spends a minute on it to believe you can do the tasks in the posting. It is a piece of evidence, sorted for a busy reader. Everything below follows from that.

Three consequences are worth keeping in mind as you write:

  • The reader skims. Headings, short bullets and a clean layout decide whether your best line is ever seen.
  • Software often reads it first. Many employers use an applicant tracking system that parses your file into fields. A plain layout survives that; a two-column design with text boxes often does not.
  • One resume does not fit every job. The version that gets interviews is the one that uses the posting’s own words for skills you really have.

Step 1: Gather your raw material

Do not open a template yet. Open a blank document and dump everything, in any order, with no editing:

  • Every job, internship, freelance gig and volunteer role, with rough dates.
  • For each one, what you actually did in a normal week, and anything you are proud of.
  • Numbers you remember: people served, money handled, targets hit, time saved, team size.
  • Education, courses, certifications and the year you finished them.
  • Tools, software, languages and methods you can use without looking things up.
  • Projects outside work that show a relevant skill.

This list is the source for everything after it. Most weak resumes are weak because the writer started formatting before they had remembered their best material. If you have little paid experience, our guide to a resume without work experience lists the places people usually overlook.

Step 2: Choose a format

There are three common layouts. For almost everyone, the first is the right one.

FormatHow it is orderedBest forWatch out for
Reverse-chronologicalExperience first, newest job at the topMost applicants with any work historyGaps are visible, so be ready to explain them
Functional (skills-based)Skill groups first, job list short or missingRarely a good choiceRecruiters often read it as hiding something
Combination (hybrid)Short skills section, then full experienceCareer changers with transferable skillsEasy to make it two pages of repetition

Whichever you pick, keep the design simple:

  • One column, standard headings (“Experience”, “Education”, “Skills”).
  • A common font at 10 to 12 points, with consistent spacing.
  • No photos, tables for layout, icons or text inside graphics.
  • Save as PDF unless the employer asks for Word.

Step 3: Write the contact line

This is the shortest section and the one people get wrong most often. Include:

  • Full name, larger than the rest of the text.
  • City and region (a full street address is no longer expected).
  • One phone number and one professional email.
  • One relevant link, such as a LinkedIn profile or portfolio, if it adds evidence.

Leave out date of birth, marital status and a photo unless you are applying in a country where they are standard. Put all of this in the body of the page, since some parsers skip headers and footers.

Step 4: Write a short summary

A summary sits under your name and answers “who is this, and why should I keep reading?” in three sentences:

  1. Who you are: your role or field and your level of experience.
  2. Your best evidence: one or two achievements that match the job.
  3. What you want: the kind of role you are applying for.

For example: “Customer support lead with five years in software companies. Built the team’s help-centre library and cut repeat tickets on the three most common issues. Looking for a support operations role in a growing product team.”

Write this section last if it feels hard, because it is easier once the experience section exists. There is a longer walkthrough in how to write a resume summary.

Step 5: Write your experience as results

This is where a resume is won or lost. For each role, list the employer, your title, the location and the dates, then three to six bullets. The bullets are what the reader actually judges.

The common mistake is writing duties. A duty says what the job was. A result says what you did with it. Use this pattern:

Action verb + what you did + the result or scale, with a number where you honestly have one.

Duty (weak)Result (strong)
Responsible for answering customer emailsAnswered 40+ customer emails a day and kept the first-reply time under two hours
Helped with social mediaPlanned and posted three times a week on two channels, growing followers from 800 to 2,100 in six months
Worked on the checkout pageRebuilt the checkout form validation, removing the most common error customers reported
Did stock countsRan the weekly stock count for a 200-item store and flagged shrinkage to the manager

A few rules keep bullets strong:

  • Start with a verb in the right tense: past for old jobs, present for your current one.
  • Put the most relevant bullet first in each role, since many readers stop after one.
  • Use real numbers only. If you do not know a figure, describe the scale in words instead of guessing.
  • Cut filler like “various”, “assisted with” and “responsible for”.

Turning a list of duties into bullets like these is the slowest part of making a resume. If you are stuck, you can paste what you actually did into InstaResume and get draft resume bullets back in seconds. It is free to try with no signup, and it works only from what you give it, so it will not invent employers or numbers. Treat the output as a draft: check every line against what really happened and keep the ones that are true. Our resume bullet point generator guide covers how to judge those drafts.

Step 6: Add education, skills and the extras

Education. List your degree or qualification, the institution and the year. New graduates can put this above experience and add relevant modules or a strong grade. Everyone else keeps it short and below experience.

Skills. List the tools and abilities you can demonstrate, grouped if the list is long (for example, “Software”, “Languages”, “Methods”). Skip soft skills stated as single words, such as “hard-working”; show them in your bullets instead. How to list skills on a resume goes into which skills to include and where.

Extras, only if they add evidence. Certifications, volunteering, publications, awards or languages. An empty or padded section does more harm than leaving it out.

Step 7: Tailor it to the job you are applying for

Your resume is now a solid general version. Keep that file as your master copy, and make a tailored copy for each application. Tailoring usually takes these moves:

  1. Read the posting and highlight the skills, tools and duties it repeats.
  2. Make sure each one you genuinely have appears on your resume, in the posting’s own wording.
  3. Reorder bullets so the most relevant ones come first in each role.
  4. Rewrite the summary’s last sentence to name this kind of role.
  5. Cut bullets that do nothing for this job to keep the page tight.

Tailoring is what gets a resume past keyword filters and in front of a person, and it is also the step people skip when they apply to many jobs at once. We have a full walkthrough in how to tailor a resume to a job description. To speed it up, InstaResume takes your experience plus the job posting and returns bullets or a cover letter aimed at that posting, using keywords drawn from the listing and only the experience you pasted.

Step 8: Check it before you send it

Run through this list before every application:

  • Length: one page for under about ten years of experience, two at most beyond that.
  • Spelling and names: the company’s name, the job title and your own contact details, letter by letter.
  • Consistency: the same date format, tense and bullet style throughout.
  • File: a PDF named with your name and the role, such as “Jane-Doe-Support-Lead.pdf”.
  • A parse test: copy all the text from your PDF into a plain text file. If the order is scrambled or sections are missing, a tracking system will struggle too.
  • A second reader: someone who has not seen it before, reading it for one minute. Ask what they remember.

Then write a short cover letter if the application allows one; how to write a cover letter has a four-paragraph method you can reuse.

When the manual way is enough

You do not need any tool to make a good resume. The manual route above is the right one if:

  • You are applying to a handful of jobs and can spend time on each.
  • You already write well and find bullets come easily once your material is gathered.
  • Your field has strict conventions, such as an academic CV or a federal application, where you should follow the specific format the employer publishes.

A tool helps most in the two places this guide calls slow: turning raw duties into result-shaped bullets, and tailoring the same resume to many postings. Either way, the resume you send should contain only things you can talk about confidently in an interview.

Common mistakes to avoid

  • Starting with a fancy template and fitting your content to its boxes.
  • Listing every duty from the job description instead of what you achieved.
  • One version for every job, with none of the posting’s words in it.
  • Unexplained gaps. A short line such as “Career break: caring for a family member” is better than silence.
  • Inflated claims. Anything on the page is fair game in an interview, and made-up numbers are easy to probe.

Quick recap

  1. Dump all your material into one rough list.
  2. Pick a simple reverse-chronological format.
  3. Write a clean contact line.
  4. Write a three-sentence summary.
  5. Turn duties into result-shaped bullets.
  6. Add education, skills and only the extras that help.
  7. Tailor a copy to each job posting.
  8. Check length, spelling, file and parsing before you send.

Do those eight steps once and you have a master resume. After that, each new application is mostly step 7, which is where most of the interviews come from.
