Some UK job postings are now attracting more than 20,000 applications each, and application volumes across several sectors are up 40% year on year, according to recruitment trends analysis from Oleeo chief executive Charles Hipps. Hiring teams are absorbing that surge without adding recruiters, which means the sorting has to happen somewhere else. It's happening in software, before a person ever opens your CV.
The maths behind the shift
The UK vacancy count is actually falling, not rising: the ONS recorded 707,000 vacancies in the March to May 2026 period, down 19,000 from the previous quarter. Fewer open roles, chasing a labour market where more people are applying to each one. That combination is what pushes application volume per role so high, and it's why a recruiter who might once have read 150 CVs for a role is now facing several thousand.
No recruitment team scales headcount 40% a year to keep pace with that. Instead, the screening step moves upstream, into an applicant tracking system that scores, ranks, or filters candidates before a human sees a shortlist.
AI screening has gone from pilot to default
Use of AI across HR tasks climbed to 43% in 2026, up from 26% in 2024. That's not a niche group of early adopters anymore, it's close to half of HR functions using AI somewhere in their process, and screening is one of the most common applications because it's the highest-volume, lowest-judgment task in the pipeline.
Candidates have noticed and don't trust it much. In a widely cited Gartner survey, only 26% of candidates believe AI evaluates them fairly, even though 52% assume their application is being screened by it. That gap between what people suspect is happening and what they think is fair is worth sitting with for a second: most job-seekers now assume a machine reads their CV first, and most don't think that machine is being kind to them.
There's a legal dimension too. A class-action lawsuit filed against Workday alleges its AI screening tools discriminate against applicants by race, age, and disability, and EU AI Act obligations for general-purpose AI systems began taking effect in August 2026, raising compliance expectations for vendors and employers using hiring tech. None of that resolves quickly, but it confirms these systems are consequential enough to be litigated and regulated, not just used quietly in the background.
What this means if you're applying for a senior role
Executive and senior candidates sometimes assume ATS screening is a junior-level problem, something that catches graduates applying to 200 jobs a week, not someone with 15 years and a shortlist of target companies. The volume numbers say otherwise. If a role you want gets thousands of applications, an AI system is doing first-pass filtering on it regardless of seniority, and a CV written for a human reader first (dense prose, clever formatting, a narrative that only makes sense after the second paragraph) can get filtered out before that human reader ever exists.
The practical fix isn't complicated: make sure the language in your CV mirrors the language in the job description, keep formatting simple enough for a parser to read cleanly, and front-load the specific outcomes a screening system is likely scoring against rather than burying them in a paragraph. It's the same CV, written to survive a step in the process that didn't used to exist.
If you want to see where your own CV would land against a specific job description before you submit it, that's exactly what the ATS Checker and JD Decoder on Executive Career Toolkit are built to show you.
