Understanding how to tell if a CV is written by AI, and how to make a CV AI-friendly, is critical, especially in the UK market, where recruiters are increasingly wary of generic, algorithm-generated submissions.

How to tell if a CV is written by AI

There are a few red flags that may indicate your CV was generated, or heavily edited, by AI:

  • Overly polished, repetitive language

    Bullet points like ‘Managed integration strategies,’ repeated sentence structures, or fancy words like ‘relentless’ without personal context. That uniform tone is a hallmark of AI writing.

  • Generic achievements

    Vague statements like ‘improved company performance’ without numbers or context can ring hollow. Genuine CVs often feature specifics tied to the candidate’s experience.

  • Skill-mismatch

    Listing advanced skills (e.g., Python in a marketing CV) may point to automated content generation.

  • Lack of personal anecdotes

    A CV that feels templated (missing employer names, worked projects, or individual contributions) lacks authenticity.

Do employers actually detect AI CVs, and do they care?

UK recruiters are growing cautious: many report seeing homogeneous AI-generated submissions with minimal personality or individual detail. Some organisations (e.g., Deloitte, EY, KPMG) have issued explicit guidance against AI use in applications. 

That said, AI detection tools remain unreliable. Some studies show less than 70% accuracy and bias against non-native writers. 

Rather than relying on detectors, employers assess consistency, credibility, and context. A well-customised, human-centred CV still wins.

How to make a CV AI-friendly (and human-approved)

To create a CV that clears ATS and human scrutiny:

1

Use concise formatting

Stick to simple headings, skip text boxes or fancy formatting, and export as PDF.
2

Use targeted keywords, without stuffing

Align language with the job description but avoid overusing terms that look like keyword dumping.
3

Keep achievements specific

Use the CAR formula (Context, Action, Result) to describe each role.
4

Humanise your tone

By right-clicking on the job application page

Edit any machine-generated phrasing to include true perspective, your voice, or personal storytelling.and selecting 'View Page Source,' you can search for keywords like 'ATS,' 'Taleo,' or 'iCIMS' to identify the software in use.

Do AI CVs get rejected?

Yes. Employers are getting frustrated with ‘sea of sameness’ applications. When many candidates use AI in the same way, submissions become monotone and indistinguishable. Recruiters are responding with psychometric tests, structured interviews, and deeper vetting. 

Plus, CV exaggeration or falsification (even if AI-assisted) can cost you offers or even legal consequences. UK studies show 1 in 5 people admit to inaccuracies on CVs, and systems now spot those inconsistencies more regularly.

Common AI CV tells recruiters spot instantly

  • Overuse of em dashes

    AI often uses em dashes in unnatural places and too often.

  • Excessive use of the word ‘professional’

    ‘Results-driven professional’ appears in 80%+ of AI CVs. It’s vague, and over-used. 

  • Mirrored bullet structure

    Every bullet starting with the same verb. 

  • Generic, unprovable claims

    ‘Detail-orientated,’ ‘hard-working,’ ‘dynamic thinker’ without evidence.

  • Lack of numbers or context

    AI content often skips quantifying achievements. 

  • Missing location or contact info

    AI CVs sometimes miss practical info, such as postcodes, cities, or LinkedIn links.

  • Misaligned skills for the job

    Irrelevant or oddly placed skills due to broad scraping.

  • Overly long CVs with filler content

    AI often adds fluff to pad out experience, leading to 3+ page CVs. 

  • Too-perfect grammar or robotic content

    Ultra-consistent structure and tone can feel impersonal or lacking nuance.

  • No personalisation to the job description

    AI-generated CVs often ignore the actual job description, missing clear tailoring.
