We traced four of the most repeated numbers. Two have no published evidence at all, one is real but usually misread, and one has no source but happens to match today's data.
“75% of CVs are rejected by an ATS before a human sees them.”
UnsupportedThe figure comes from a 2012 sales pitch by Preptel, a company that sold CV optimisation; no methodology was ever published. Many applicant tracking systems (ATS) simply store and search applications. What’s true: if an ATS can’t read your file, your details can be lost, and knockout questions on the form do screen people out.

“Recruiters spend 6 seconds on your CV.”
MisleadingThe number comes from Ladders’ eye-tracking studies: about 6 seconds in 2012 and 7.4 seconds in 2018. It measures the first skim, when a recruiter decides whether to keep reading, not how long they spend evaluating a CV they’re interested in. The same study found simple layouts with clear headings did best.

“Every corporate job gets 250 applications.”
Unsourced, but closeThe number has circulated for over a decade, usually credited to Glassdoor, for example in a 2016 Built In article, but without a link to any study. Recent platform data happens to land nearby: about 244 applications per role on Greenhouse in 2025, and more than 300 per hire on Ashby. Treat it as a rough average; it varies hugely by role and company.

“80% of jobs are never advertised.”
UnsupportedNo study supports it. Career centres trace it to anecdotes, informal surveys and 1970s–80s job-search books such as What Color Is Your Parachute?. Referrals and internal moves do fill some roles before they’re posted, so networking helps; the 80% figure just isn’t evidence of how many.
