In short
- Gather all your facts first, in one sitting, before writing anything. Look for numbers in rotas, reports and appraisals.
- Write the experience section first and the summary last.
- Keep the layout plain so the facts do the talking.
- Tailor a copy for each job and check the file before you send it.
A resume has one job: to make a stranger want to talk to you. It is not your biography and it does not have to cover everything you have ever done. It has to show, in under a minute of reading, that you fit the role in front of them.
That is a writing task, and like most writing tasks it goes faster in the right order. This guide walks the whole job once, start to finish, and hands each big topic to its own deeper guide along the way.
Gather the facts before you write a word
Most of the pain of resume writing is remembering, not writing. So remember first, in one sitting, with the writing switched off.
Collect your employers, job titles and dates, your degrees, licenses and certificates with their years, and the work you are proud of: things you built, problems you fixed, anything with a number attached (how many, how much, how often). Pull up old appraisals, project notes and sent emails if they help. Nothing needs to be polished yet. A messy list of true facts is the raw material for everything below.
Keep this master list somewhere safe even after the resume is done. Every future application starts from it.
Where the numbers hide
Most people say they have no numbers. Usually they have plenty and have never looked. Try your appraisals and review notes, your rota or shift pattern, sales or call reports, the till or handheld that counted your work, old emails where you reported progress, and the people you worked with. Asking a former colleague "roughly how many a day did we do?" often gives you a figure you can stand behind.
Before
Delivered parcels in the local area.
After
Drove a mixed town and village route, delivering about 120 parcels a day, and did the van's safety checks each morning before loading.
Why it works: The 120 came from his handheld, which counts each drop. The route and the van checks came from asking him to talk through a normal day.
If there is truly no number, describe scale (how big), frequency (how often) or who relied on you. "Opened the shop alone on Sundays" needs no figure to show that someone trusted you. Never round a guess up into a fact. If you would not repeat the number to the manager who was there, leave it out.
The order of work
Gather the facts
Employers, dates, degrees and everything with a number attached, in one unpolished list.
Write experience first
The hardest section gets your freshest attention: three to five result bullets per job.
Fill the supporting sections
Education, skills, projects and contact details. Quicker once experience exists.
Write the summary last
Three or four lines that trail the page below. You cannot summarize what is not written.
Keep the format plain
One column, a normal font, clear headings, a sensible length.
Tailor, check, send
Adjust a copy for the posting, read it out loud, then check what software sees.
The order saves time: every later step leans on the one before it.
The order matters for one reason: the hardest section carries the most weight, so it should get your freshest attention, and the sections that depend on other sections should come last.
Write the experience section first
Experience is the section recruiters read most carefully, and the one that takes the longest to write well. Start here while your energy is high.
For each job: title, employer, dates, then three to five bullets. Each bullet should say what changed because you were there, not what your job description said.
Before
Processed payroll for staff.
After
Paid about 300 warehouse and driving staff each fortnight, checking every overtime claim against the clock-in records before the run.
Why it works: The 300 came from the headcount in the payroll system. The overtime check is the part of the job she did well, and the old line hid it.
Turning duties into lines like that is a skill of its own, and the guide on bullet points teaches it with more examples.
On the page, a finished experience section looks like this:
The bullets from this guide on a real page, drawn with the same templates the Builder uses. A fictional sample.
Then the supporting sections
With experience done, the rest is quicker. Education with the newest entry first. A skills section with the tools and abilities the role asks for, grouped so they can be read in a glance. Projects, certificates or volunteering if they add evidence the jobs do not. Your contact details at the top: a professional email, one phone number, your city and region, and a LinkedIn or portfolio link if it is ready to be seen.
If you are early in your career and the experience section feels thin, lead with education and projects instead. The guide for first resumes covers that order in full.
Write the summary last
The three or four lines at the top are a trailer for the page below, which is why they come last: you cannot summarize what does not exist yet. Say who you are, what you are good at, and the one or two results that prove it. No adjectives that anyone could claim.
Before
Caring and hardworking nurse with excellent communication skills.
After
Registered nurse with five years on a busy surgical ward. Strong on pre-op checks and discharge teaching, and looking for a day surgery role.
Why it works: Every fact came from the page below the summary. Swapping adjectives for what she does lets the reader see the fit at a glance.
The resume summary guide has more rewrites that show the difference.
Keep the format boring, in the good way
One column is safest. A normal font. Clear section headings. One page or two depending on how much strong material you have, and no padding to reach two. Save it as a PDF unless the posting asks otherwise.
A plain layout is not a missed opportunity. It is what lets your facts, rather than your formatting, do the talking.
Tailor it before each application
The resume you just wrote is your master copy. For each job, make a copy and adjust it: lead with the experience this posting cares about, use the posting's own words where they are true of you, and cut what this employer does not need. It takes about twenty minutes, and it is time well spent. The guide on tailoring a resume to a job shows the routine.
Check it before you send it
Read it out loud once: your ear catches what your eye forgives. Check every date, number and name. Ask one person you trust to read it cold and tell you what they remember.
Then check what software sees. Many employers collect applications in tracking software that turns your file into text before a person reads it, and the free ATS check shows how your file reads to one, so a layout problem surfaces now and not after you have applied.
Common questions
- How long should writing a resume take?
- Spread it over two or three sittings rather than one marathon. An evening for gathering facts, a sitting for the experience section, and a shorter one for the rest and the checks. Rushing the experience section is the expensive mistake.
- Should my resume say "I"?
- Leave it out of the summary and the bullets. Write "Built a stock sheet", not "I built a stock sheet". The reader knows the page is about you, and dropping "I" keeps each line short. Your cover letter is the place to write in the first person.
- What if I cannot remember my exact dates?
- Look before you guess. Payslips, tax records, offer letters, old emails and bank statements showing your first and last salary will usually settle it. If you can only be sure of the year, write years only, and do it the same way for every job on the page. Never invent a month.
