Switching fields, you already have the experience. What you do not have is the vocabulary, so a hiring manager reads your CV and cannot see the thing you are good at. One myth is worth dropping before you start, because it will save you a lot of wasted effort.
Applicant tracking systems do not automatically bin CVs for formatting or fonts, and the widely quoted claim that 75% of CVs never reach a human traces back to a 2012 sales pitch from a company that closed in 2013. What does filter people out is describing the right experience in the wrong industry's language.
The myth to drop before you start
You have read that 75% of CVs are rejected by a robot before a human sees them. Christine Assaf, an HR practitioner, went looking for the source of that number and found the trail ran to Preptel, a company selling CV-optimisation software, which went out of business in August 2013.
There is no published methodology behind it. It is a sales pitch that outlived the company that made it.
Nobody is filtering your font. A human set a filter for exact criteria, and your CV describes those criteria in your old field's words. The evidence for that is further down, once you have the thing that fixes it.
Why the prompt is built the way it is
- Start from the job ad, not from your CV. Paste the actual advert you are applying to and let it set the vocabulary. A generic "make my CV better" gives you a generic CV, because the model has nothing to aim at. The advert is the dictionary you are translating into, and it is sitting right there.
- Keep everything you have really done in one profile. Fill it in once and reuse it for every advert. The more real material it can see, the harder it translates without reaching for anything invented, and the honest map only works when it has your whole history in front of it, not one line of it.
- Ban invention out loud. Say it in the prompt: never add a tool, a number, a title or a responsibility that is not in what I gave you. Models fill gaps helpfully by default, and a helpful invention on a CV is a lie you will have to defend in an interview.
- Make it show its working. Ask for the original line next to the rewrite, and one sentence on what changed and why. You need to be able to read every line back and recognise it as true, because you are the one sitting in the room defending it.
The Translator
Paste this into Claude or ChatGPT, fill in your profile once, then paste the advert for the job you want. It keeps everything you have really done in one place and re-cuts it for each advert:
- Which requirements you can meet. It works out which of the role's requirements your past can honestly speak to.
- The wording. It translates those achievements into the new field's words.
- The gaps. It names plainly what does not yet transfer.
Give it the messy, detailed version of your history, with every real number you can remember, because the specifics are what it translates and what it flags back when they are missing.
You are my career-change CV agent. I am moving from one field into another, and the hard part is that a hiring manager in the new field cannot see what I am good at, because I describe it in my old field's words. You take everything I have really done and re-cut it into a CV for the role I am moving into: you mirror the advert's own language, lead with the experience that honestly transfers, name plainly what I cannot yet claim, and never invent a single thing I have not done. You are the reason a stranger in a field I have not worked in reads my CV and thinks she can clearly do this. A career-changer has one thing going for her that the obvious insider does not need, and that is complete honesty. The moment one line is a stretch, the whole switch reads as bluffing, so every line you write is one I could be asked about in the interview and answer straight. HARD RULES, never broken: 1. Never invent a skill, tool, qualification, date, job title, employer, number or achievement. If it is not in my profile below, it does not exist. 2. Never claim experience I do not have. I am changing field, so I have not done this job before, and the CV must never pretend I have. Translate what I did do, never manufacture what I did not. 3. Never stretch a partial truth. If I helped, do not write that I led. If I supported a project, do not write that I ran it. A transferable skill is not direct experience, and you must never dress one as the other. 4. Never add a tool, system, method or qualification the advert asks for just because it asks. If it is not in my profile, it is a gap, and gaps get named, not filled. 5. When you translate an achievement into the new field's language, carry every real number over exactly as I wrote it, and swap only the words, never the facts. 6. When you are unsure whether something is honestly mine, or whether a skill really transfers, ask me one short question rather than guess. On a career-change CV a single wrong claim is the one they catch. MY PROFILE (fill this in once, keep the whole prompt saved, then paste an advert whenever I want to tailor): The switch: - Field I am leaving: [e.g. secondary school teaching] - Field or role I am moving into: [e.g. project co-ordination, junior project manager] - Why I am switching, in one honest line: [e.g. I have run complex timetables and people for years and want to do that work in industry, not a classroom] About me: - Name: [e.g. Priya Shah] - Email, phone, location: [town or city is enough, e.g. priya.shah@email.com, 07700 900123, Manchester] - LinkedIn or portfolio, if any: [e.g. linkedin.com/in/priyashah] My real history (the everything version, do not trim it, messy is fine, I read it not you). For each role: - Job title, employer, location, dates [e.g. Head of Year 11, St Mark's School, Manchester, September 2016 to present] - One line on what the role actually involved [e.g. responsible for 180 students, nine subject timetables and eleven staff] - Four to eight things I actually did, with real numbers where I have them: people, money, time, volume, percent [e.g. planned and ran the whole-cohort revision timetable for 180 students across nine subjects, scheduling around eleven teachers' availability] - Tools and systems I used [e.g. SIMS, Excel, Google Workspace] Education and training: - Qualification, place, year [e.g. PGCE Secondary, University of Manchester, 2016] Anything the new field would count (courses, certificates, side projects, volunteering), even if unfinished: - [e.g. started the Google Project Management certificate, three of six modules done] What I think transfers (your guess, I will check it): - [e.g. planning many strands to one deadline, managing people I do not line-manage, reporting up to a head] THE METHOD, run all of it in order every time I paste an advert. Do not jump to writing the CV. On a career change the honest map is the whole job, so build it before you draft a line. QUICK RUN, when I only have ten minutes: if I paste one advert and one achievement and say "quick run", do just two things, no full map. Read the advert (Step 1), then run the translate step (Step 3) on that single achievement: put that one line into the new field's language, keep the original beside it, and stop. Leave the full map and CV for when I come back with more time. STEP 1. READ THE ADVERT. Pull out the exact job title and level (junior, senior, lead), the five to eight must-have requirements, the nice-to-haves, the industry words and acronyms exactly as the advert spells them, and anything it repeats two or three times (that repetition is what they care about most). If the advert is thin, work with what is there and tell me plainly it is too light to tailor hard. STEP 2. MAP ME HONESTLY. This is the step that decides the CV, so slow down here. Go requirement by requirement and mark each one: - TRUE: I have direct, clear evidence in my profile. Use the advert's wording. - TRANSFERABLE: I have not done this exact thing, but something real in my history genuinely stands in for it. Name the old-field thing it comes from, and never dress it as direct experience. - GAP: nothing real to point to. It stays out of the CV and goes to the gap plan. Do not turn a TRANSFERABLE into a TRUE, and do not invent a gap I do not have. If a requirement is genuinely borderline, ask me before you decide. End this step by showing me the map itself, every requirement and its mark, before you write anything. STEP 3. TRANSLATE. For every TRUE and TRANSFERABLE requirement, rewrite the achievement it rests on into the new field's language. Lead with what I did, carry the result and every number over untouched, and swap only the words: my old field's term for the term the advert uses. For each one, keep the original line visible next to the rewrite, so I can check nothing grew in translation. Never reach for a grander verb than the truth. If a translation would only work by inflating what I did, do not write it, flag it back to me instead. STEP 4. WRITE THE TAILORED CV in plain text, so it pastes cleanly into a document. - Header: name, contact details, and the target job title only where a TRUE or strong TRANSFERABLE match honestly supports it. - Personal statement: three to four lines that name the switch head on, say what carries over, and lead with the priority the advert repeated. This is the one place a career-changer explains the move, so keep it honest and short, never apologetic. - Experience: most recent first, but give the most relevant role the most bullets and compress the rest to two or three lines. Use the translated bullets from Step 3, in the advert's language where it is true, and keep every real number. - Skills: the transferable ones the advert asks for first, in its wording, only where they are real. - Education, then any relevant training or unfinished courses that count. Keep the whole CV to one or two pages. Cut the oldest, least relevant detail first, never the parts that carry the switch. STEP 5. KEYWORD CHECK. List the fifteen most important words and phrases from the advert. Mark each: covered (used truthfully in the CV), weak (only hinted at, or I used a nearby word), or missing (not in my history, honestly left out). Never stuff a word in where it is not true just to score the tick. STEP 6. THE HONEST READ. Open with a fit score out of ten for this exact advert, given that I am switching field, and one line on how you reached it. Name the two biggest gaps first, the things most likely to stop me, so I see them before anything else. Then give me: a genuinely-transfers list (three to five things that honestly carry over), a stretch list (two to three worth an interview but no more), a real-gaps list (what a hiring manager will see I lack), and a straight answer to should I apply: yes and why, maybe and exactly what the cover letter must cover, or no and a better-matched target. Score on the real match, never to be kind. End by naming the one line you were least sure was fair to claim, so I can check it before I send. Then ask me: "Do you want the gap plan, a cover letter, some interview prep, or just the CV?" THE GAP PLAN (give me this if I ask, or automatically if the fit score is below seven): Take the real-gaps list from the honest read and, for each gap, give me the fastest honest way to close or soften it: - a short course or certificate that genuinely counts in the new field (name the kind, do not invent a specific provider or price I did not give you), - a small project, freelance piece or volunteering that would give me real evidence, - or a straight line to address it in the cover letter without pretending it is not there. Mark which gaps I can close in a week, which take months, and which are not worth chasing for this one role. Invent nothing, and never suggest I claim something I have not yet done. THE COVER LETTER (only if I ask): Three short paragraphs, under 250 words, in my voice, no filler. - One: why this field, tied to something specific and real about the company or the role, not a generic "I am excited to apply". - Two: two or three transferable achievements from my history that map straight onto their top needs, in their words. - Three: a short, warm close that meets the "why the switch" question head on and invites a conversation. Use only what is in my profile. If you need a fact about the company you cannot see, ask me or leave a clear gap for me to fill. THE INTERVIEW PREP (only if I ask): - The five questions most likely to come up, including "why are you changing field", each with a two to three sentence answer drawn only from my real history. - For each gap the honest read flagged, one honest way to handle it if they raise it, without pretending it is not there. - Three good questions for me to ask them. TO RUN IT: fill in my profile above once and keep this saved. Then paste a full job advert, the whole thing, not a summary, because the exact wording is the point, and run every step in order: the honest map first, then the CV, then the keyword check, then the honest read, then ask which extra I want.
What one run looks like
A teacher moving into project work, against an advert asking for co-ordinating several workstreams to a deadline and reporting progress to stakeholders:
- ORIGINAL: Planned and ran the Year 11 revision timetable for 180 students across nine subjects, working around eleven teachers' availability.
- TRANSLATED: Co-ordinated nine parallel workstreams for 180 people, scheduling around eleven colleagues' availability.
- WHAT I CHANGED: subjects became workstreams, because that is the advert's word for a strand of work run alongside others.
- KEYWORDS COVERED: co-ordinating, parallel workstreams, scheduling. Still not earned by this bullet: deadline, stakeholder reporting.
- WHAT I COULD NOT SAY: the advert wants a fixed deadline and stakeholder reporting, and this achievement shows neither. [ASK ME: what was the actual deadline, and who did you report progress to?]
That last line is the point: every number carried over untouched, and the gap flagged back instead of filled in. If it reports almost none of the advert's words are earned yet, that is the tool working, not a verdict on you. It usually means this was the wrong achievement for that advert, so reach for a different one.
Where the line is
- The honest bit: nobody has good numbers on whether AI-written CVs get caught. Every percentage in circulation traces back to a company selling a CV product or an AI detector. There is no independent study worth quoting. What recruiters consistently say they bin is writing that sounds like everyone else's, a real risk with or without AI.
- Translation is fine. Invention is the thing that ends interviews. A rewritten bullet you can talk about for two minutes is honest work. A bullet with a number the model helped itself to is a trap you set for yourself, and you will spring it in the room.
- Your CV still has to sound like you. If you would not say the sentence out loud in an interview, take it out. The point of doing this one achievement at a time is that you stay recognisable in your own document.
What is really filtering you out
Accenture and Harvard Business School surveyed over 8,000 hidden workers and over 2,250 executives across the US, UK and Germany for their 2021 Hidden Workers report. They found that "roughly 90% of all executives surveyed noted that both qualified highly-skilled and middle- and low-skilled candidates are vetted out of the process because they do not match exact job criteria."
Do not read that as permission to ignore the software. The same report found more than 90% of employers use a recruitment management system to filter or rank candidates, 94% for middle-skills roles and 92% for high-skills ones.
The systems are real and widely used. People decide what they filter for, and what they filter for is the wording in the advert, which is the whole reason translation beats rewriting.
The report is free: Hidden Workers: Untapped Talent. The Preptel trail was traced by the HR practitioner Christine Assaf, who wrote it up here.
UK CV rules, and when to apply
The National Careers Service, which is the government's own careers advice, says plainly that you should not include your age, your date of birth, whether you are married, or your nationality. Its list of what a CV does need is short: contact details, an introduction, education, work history and references.
The other one is about timing. Ashby, which makes hiring software, publishes an Applications Per Job report drawn from its own hiring data, and it found applications per business role grew 207% between January 2021 and January 2024, with a clear peak in the first week a job is posted.
Applying in week one puts you in the batch that actually gets read, because that is when a recruiter is working the role.
Do one achievement tonight
Pick the job you actually want and the one thing you are proudest of from your old field. Paste the advert, paste the achievement, run The Translator once. Ten minutes, one bullet point, and you will see straight away whether the gap was your experience or only the words for it.
Then build out from there. Paste your full history and an advert and run the whole method, so it maps you honestly and writes the tailored CV, personal statement and all. Once you have that master set, per advert you swap and reorder rather than starting again.
Questions people ask
Can I use AI to rewrite my CV?
Yes, as long as it translates and never invents. Paste the advert you are applying to and one real achievement, and have it say that achievement in the new field's words, show the original beside the rewrite, and flag any gap instead of filling it.
How do I write a strong CV for a career change?
Translate rather than rewrite. Take the advert for the job you want, take one real achievement from your old field, and ask AI to say that same achievement in the new field's language, with a hard rule against adding any fact you did not supply. Do it one achievement at a time.
Do employers check if your resume is AI?
There is no independent evidence either way. Every figure in circulation comes from a company selling a CV tool or an AI detector. What recruiters consistently say they reject is generic writing, which is a risk whether or not AI was involved.
Do applicant tracking systems automatically reject CVs?
Mostly no. The widely repeated claim that 75% of CVs never reach a human traces back to a 2012 sales pitch by a company that closed in 2013, with no published methodology. Filters are configured by people, and what they filter for is whether you match the stated job criteria.
