How to Write a Resume That Doesn't Sound AI-Written

The three things that make a resume sound human (and not AI-written): (1) specific numbers — recruiters’ eyes lock onto digits before words. (2) Proper nouns — real client names, real project names, real cities. (3) Variety in sentence structure — AI defaults to parallel construction; humans don’t. Skip any one and your resume joins the AI-pile. Drill below.

If you have ever asked ChatGPT to write your resume bullets and felt that something was off about the result — too smooth, too clean, too obviously confident-sounding — you have already noticed what every experienced recruiter has been noticing for the last two years. After 24 years of training working professionals in Singapore — including coaching mid-career professionals through CV rewrites — I can tell you the gap between an AI-drafted resume and a human-written one is now the single fastest filter in the recruiter’s stack.

Here is a useful way to think about it. An AI-written resume is like a printed form mailed in a hand-written-letter world. Technically correct. Structurally fine. Visibly mass-produced. The skill isn’t avoiding AI — it’s using AI to scaffold and then rewriting the bullets in your actual voice, with the specific details only you would know. This article gives you the rewrite drill.

1. Why recruiters can spot AI resumes in 3 seconds

The recruiter’s eye has been training itself, fast, since 2023. After 24 years of training I now hear from recruiters the same observation across industries: AI-drafted resumes are visibly different from human-written ones, and the difference is consistent enough to flag in seconds.

Three reasons recruiters spot them:

1. Volume effect. Recruiters now scan dozens of AI-drafted resumes per day. The pattern jumps out by sheer comparison.
2. Vocabulary signature. AI tools default to a specific cluster of words and phrasings. Once you know the cluster, you see it.
3. Specificity gap. The single biggest tell — AI-drafted bullets describe activities; human-written bullets describe specific outcomes. “Led cross-functional initiatives” is AI; “Led the Q3 supplier consolidation across 14 vendors, recovering $420k in annual spend” is human.

This isn’t a temporary trend that will pass. It’s a permanent shift in how resumes get filtered. The fix is permanent too — and surprisingly simple.

2. The 5 tells of an AI resume

Memorise these. Eliminate them.

Tell	Example	Fix
Vague action verbs	”leveraged”, “spearheaded”, “orchestrated”, “drove”	Replace with concrete verbs: led, built, ran, wrote, sold, hired, fired, designed
Unmodified abstract nouns	”synergies”, “efficiencies”, “solutions”, “stakeholders”	Replace with specific nouns: 14% time saving, 3 vendor consolidation, sales team of 8, the procurement director
Parallel structure	Every bullet starts: “Led X, drove Y, delivered Z”	Vary structure. Some bullets short. Some longer. Some without verbs.
The “cross-functional” tic	”cross-functional teams”, “cross-functional collaboration”	Name the actual functions: “with finance and engineering”, “across the procurement and legal teams”
Hedged success	”successfully”, “successfully delivered”, “successful implementation”	Drop the word. If you delivered, the outcome shows it.

These five tells together account for roughly 80% of the AI-resume signal recruiters spot. Eliminate them across your resume and the signal drops dramatically.

3. The specific-over-generic rewrite drill

The most useful drill for de-AI-ing a resume. Run it on every bullet.

Take any AI-drafted bullet. Ask three questions:

What’s the number? A percentage, a dollar figure, a count, a duration, a multiplier. Add it. Who was the audience? Name them. “the regional MD”, “a team of 14 engineers”, “clients across financial services”. What’s the proper noun? A real project name, a real client name (if not confidential), a real city, a real document, a real year.

Apply to a generic AI bullet:

❌ “Led cross-functional initiatives to drive operational efficiency.” ✅ “Led the Q3 2025 supplier consolidation project across procurement, finance, and legal — reducing the vendor list from 47 to 18 and recovering $420k of annual spend.”

The second version is roughly 40% longer, but it carries 4-5x the conviction with a recruiter scanning at 5 seconds per bullet. Specificity is the substrate of credibility.

The same specificity discipline drives writing professional emails generally and budget request emails specifically — numbers and proper nouns over abstract claims.

4. The 3-question test for every bullet

A faster version of the rewrite drill, runnable in 30 seconds per bullet:

1. Could a different person write this exact sentence about their work? If yes, it’s too generic.
2. Does it have a specific number, name, or year? If no, add one.
3. Does it tell what changed because of you? If not, rewrite for outcome, not activity.

Bullets that pass all three questions are unmistakably yours. Bullets that fail any of them are interchangeable with someone else’s resume — which is the AI-signature pattern.

5. What to keep from AI assistance (and what not to)

Don’t avoid AI. Use it well.

Use AI for	Don’t use AI for
Structuring sections (Experience, Education, Skills, Certifications)	Writing the bullet content verbatim
Brainstorming what to include (memory prompts)	Choosing the proper-noun details
Formatting and consistency	The 1-2 line professional summary at the top
Spell check, grammar	The cover letter (write fully yourself)
Tightening bullets you’ve drafted yourself	Generating bullets you haven’t lived

The pattern: let AI scaffold, you fill in the substance. The hybrid is far stronger than either alone — better structured than human-only, far more specific than AI-only.

The same hybrid logic applies to prospecting emails — AI drafts the structure, you write the specific reference and the personal detail.

6. Singapore-specific resume conventions

A few details that matter in the Singapore market:

• A4 paper, not US letter. Resume PDFs sized for letter paper print awkwardly here.
• 2 pages max for mid-career roles; 1 page for early-career; 3 pages acceptable only for very senior leadership roles.
• Citizenship/PR status mentioned at the top of the resume. “Singapore Citizen” / “Singapore PR” / “Employment Pass holder”. Saves the recruiter a question; matters for SFEC-eligible roles.
• WSQ / SkillsFuture / industry certifications listed under a clear Certifications section, not buried in narrative. ACTA, PMP, CPA, ACCA, AICPA, etc.
• No photo unless the industry explicitly expects one. Singapore corporate norm now skews against.
• No date of birth, ID number, or marital status. Singapore recruiting has moved away from these for fair-employment reasons (see TAFEP for current guidance).

7. The 60-second human polish at the end

After you’ve drafted the resume — AI-assisted or not — run a final pass. Sixty seconds. Catch the residual AI signature.

Three quick checks:

1. Read every bullet aloud. AI-drafted text reads fluently but feels mechanical when spoken. Stumbles in your reading are usually places to rewrite.
2. Look for the same verb twice. AI tends to over-use a small verb set. Vary.
3. Ensure each bullet has at least one of: a number, a proper noun, or a specific year. No bullet should be all-abstract.

Most resumes that have been AI-drafted and not human-polished fail at least one of these tests. Most resumes that have been polished pass all three.

A pattern from the training room. I once worked with a recruiter friend who told me her current resume-screening time was 3 seconds per CV — and that AI-drafted ones now triggered an automatic defer-to-later response. “It’s not that they’re bad. It’s that I can’t tell anything about the person from them.” We tested this with a CV that had been ChatGPT-drafted, then run through the specific-over-generic drill — replaced 12 generic bullets with 12 specific ones, kept the structure, took 90 minutes. She pulled it from her defer pile to her interview pile within 5 seconds. After 24 years of training, the same lesson: specificity is the antidote to AI tone. It’s not about avoiding AI — it’s about adding what AI can’t.

The natural sequence: draft with AI → identify and eliminate the 5 tells → run the specific-over-generic drill on every bullet → apply the 3-question test → calibrate for Singapore conventions → 60-second polish out loud.

The same drill-then-deploy logic from building soft skills generally applies. Rewriting a CV is a low-frequency, high-stakes task. Most professionals do it 2-5 times across their career. The 90 minutes invested in proper de-AI-ing is the single highest-ROI editing work most professionals will do in a year.

I hope you find one drill in this article that fits your next CV update. Pick the smallest one — running the 3-question test on the first three bullets — and try it. That is enough. The rest builds from there.

If you want a structured course on professional written communication broadly, Writing Professional Emails (WSQ) is the 2-day course covering the underlying writing skills. SkillsFuture credit eligible. For the interview that follows the resume, Communicate with Confidence (WSQ) is the natural pairing.
