How to build a master resume

What goes in a master resume

Think of it as a career archive, not a polished document. The goal is completeness, not brevity. Include everything now and cut later when you tailor.

Most people underestimate how much belongs here. A role you held for three months still produced skills and context. A volunteer project still shows initiative. A certification you let lapse still signals knowledge.

• Every job title, employer name, city, start month and year, end month and year
• Three to eight bullet points per role describing what you did, how you did it, and what resulted
• Every hard skill: software, languages, tools, platforms, certifications, licences
• Every soft skill with a concrete example attached, for example 'led a cross-functional team of six to ship a product two weeks early'
• Education: institution, degree or qualification, field, graduation year, GPA if above 3.5 or a first-class equivalent
• Awards, publications, patents, conference talks, open-source contributions
• Volunteer work, board memberships, professional associations
• Languages and proficiency levels using a standard scale such as CEFR

How to write strong bullet points for each role

Weak bullets describe duties. Strong bullets describe outcomes. The difference is what a hiring manager remembers.

Use the formula: action verb, what you did, the result or scale. For example, 'Reduced customer onboarding time from 14 days to 6 days by redesigning the intake form and automating three manual steps.' That one sentence answers what you did, how, and why it mattered.

Write every bullet in past tense, even for a current role. It reads more cleanly when you paste it into a tailored resume later. Keep each bullet to one or two lines. If a bullet needs three lines, split it.

• Start with a strong verb: built, reduced, led, negotiated, launched, automated, trained, secured
• Add a number wherever you can: dollar amounts, percentages, team sizes, time saved, volume handled
• If you cannot find a number, describe the scope: 'across a portfolio of 40 enterprise clients' is still specific
• Write two or three versions of the same bullet at different levels of detail so you can match the depth a job posting calls for

How to organise the document

Format does not matter much because you will never send this file. Use whatever keeps you organised. A Google Doc or a plain text file both work. What matters is that you can search it quickly.

Put your most recent role at the top and work backwards. Within each role, group bullets by theme if you had a broad scope: one cluster for people management, one for technical work, one for commercial results. That makes it faster to grab the right bullets when a job posting emphasises one area over another.

Add a skills index at the top of the document. List every tool and technology you know, grouped by category. When a job posting mentions a specific platform, you can check your index in seconds rather than scanning every role.

When and how to update it

The master resume only works if it stays current. The best habit is to update it within a week of anything changing: a new project wraps up, you learn a new tool, you get promoted, you finish a course.

Set a recurring calendar reminder for the first of every month. Open the document, spend ten minutes, and ask yourself three questions: Did I finish anything worth recording? Did I learn anything new? Did my responsibilities change? Most months the update takes less time than the reminder.

In the US, Canada, the UK and Australia, employers increasingly use applicant tracking systems that parse resumes for keywords. Keeping your master resume detailed means you will always have the right language available to match a posting without fabricating anything.

1. Open the document on the first of each month
2. Add any completed projects with outcomes and numbers
3. Add any new tools, certifications, or skills
4. Update your current role's bullet points if your scope changed
5. Save and close

How to tailor from your master resume

Read the job posting carefully and identify the three to five things the employer cares about most. These are usually in the first paragraph of the description and in the required qualifications list.

Search your master resume for bullets and skills that match those priorities. Copy them into a new document. Reorder them so the most relevant items appear first. Cut anything that does not support the story you are telling for this specific role. A tailored resume for most roles should be one page for under ten years of experience and two pages for more.

Change nothing factual. Adjust the framing and the order, not the substance. If a posting emphasises stakeholder communication and you have a bullet about presenting quarterly results to a board of twelve, move that bullet to the top of the relevant role. If the posting does not mention that skill at all, leave the bullet out of this version.

Using Break-In Bad to speed up the process

If you want to build a polished starting point rather than a raw archive, Break-In Bad's assistant Omar can build a resume from scratch for 30 credits or enhance an existing one for 15 credits through a conversation of up to 20 questions where you tap or type your answers.

Once your resume is in the system, Omar writes a tailored resume and cover letter for each job from facts you confirm, then applies on Greenhouse, Lever, Workday and other employer sites with a screenshot as proof. That means your master resume work translates directly into faster, more accurate applications without re-entering information each time. New accounts get 50 free credits to start.
