AI is flooding London tech hiring with inflated CVs

AI is reshaping how London employers screen tech candidates, with Robert Half reporting a sustained rise in AI-generated job applications that look relevant on paper but fail to match candidates’ actual skills.

Matt Weston, Senior Managing Director for UK and Ireland at Robert Half, said the trend is most visible in London tech roles, where employers are now spending longer validating whether listed experience is genuine.

International data from the firm shows 65% of US hiring managers, 64% in Canada and 66% in Brazil report AI-tailored CVs are creating verification problems, while 37% of Australian hiring managers say screening has become harder.

The shift breaks a long-standing recruitment model that treated the CV as a reliable first filter.

Generative AI tools can now produce applications tailored line by line to a job description in minutes, producing documents that read as polished and highly relevant but often closely resemble each other.

Weston said entire applications can be matched to job descriptions in this way, leaving recruiters less able to evaluate CVs at face value.

The practical consequence is that early-stage screening, which used to surface clear differentiators, increasingly produces a homogenous shortlist.

For London’s tech sector the effect is particularly pronounced because tech roles attract higher application volumes and candidates are typically more fluent with AI tools.

Robert Half said the result is a candidate pool where CVs appear relevant but do not align with actual skills or experience, forcing hiring managers to dig deeper at the interview stage to test whether claimed competencies hold up in practice.

That gap between written application and demonstrated skill is what Weston describes as blurring the line between reality and misrepresentation.

Longer hiring cycles for British tech employers

The downstream effect is slower hiring.

Weston said employers are already cautious in volatile economic conditions, and the rise in AI-generated applications is pushing time-to-hire upwards as recruiters review more applications, run deeper interview processes and rewrite job descriptions to filter out generic responses.

For UK tech firms competing for engineers, product managers and data specialists, that lengthening cycle has real cost implications and risks losing candidates to faster-moving rivals.

The response Weston advocates is a return to human judgement at the evaluation stage rather than reliance on automated keyword matching, which generative AI now defeats easily.

That includes structured interviews focused on practical problem solving, technical assessments that test live capability rather than written explanation, and reference checks that verify specific claimed achievements.

None of these is new technique, but the volume of AI-tailored applications is making them mandatory rather than optional.

What UK jobseekers should do now

• Use generative AI to sharpen and structure your CV, but never let it invent or inflate experience you cannot demonstrate in an interview
• Prepare specific, measurable examples from past projects, including metrics, technologies used and your individual contribution, ready to discuss in detail
• Practice live technical assessments and work-sample tests in advance, as these are increasingly used to verify the skills listed on your CV
• Tailor each application manually around a genuine match with the role rather than relying on AI to mirror the job description word for word
• Build a verifiable portfolio, GitHub profile or case study library that demonstrates capability beyond what any CV or AI-generated cover letter can claim
