Researchers also found that candidates from historically underrepresented backgrounds are 62% more likely to be ghosted after a job interview than white candidates.
Nearly nine in 10 (88%) candidates reported that they expected to hear back from companies within one or two weeks following their initial application.
Kate Garbett, vice president for SMEs at Adecco Group, stated that ghosting candidates after a job interview was bad for organisational reputation.
Speaking to HR magazine, she said: “There’s little justification for ghosting a candidate after an interview. It's an unprofessional practice that can damage both a recruiter’s and a company’s reputation and, more importantly, significantly affect a candidate’s morale and motivation.
“Nonetheless, it happens for a variety of reasons: time pressures, uncertainty about the candidate’s fit for the role or the viability of the role itself, simply forgetting to close the loop, or just not knowing what to say.
“Ultimately, I’d urge anyone who interviews an unsuccessful candidate to take the time to explain why they are not being progressed.”

Meanwhile, the Greenhouse team found that 29% of candidates experienced a company changing the advertised salary after an interview.
Male candidates were 61% more likely to experience this than female candidates.
Candidates cited the top-three reasons they reject job offers as the salary being below their expectations (48%), having received a better offer from another company (32%) and limited or no flexible or remote work options (21%).
Garbett commented that the findings revealed gender bias in salary expectations.
She said: “The finding that men in the UK are 61% more likely to experience a salary bait-and-switch compared to women is both worrying and surprising.
“Given the ongoing gender pay gap, it’s usually accepted that men go for more pay rises and promotions than women, and are more prepared to negotiate hard for what they want financially.
“If bait-and-switch is happening disproportionately for men, it could indicate underlying biases or assumptions about gender and salary expectations.”
She added: “There’s also evidence to suggest men dream bigger than women when it comes to pay so, if a salary range is advertised, could an explanation be that they assume that they’ll qualify for the higher figure?”

Ola Kolade, employment and skills director at Business in the Community, explained that eliminating bias during recruitment would benefit employers and employees.
Speaking to HR magazine, he said: “Eliminating bias during the recruitment process and opening doors to diverse talent is not only the right thing to do; it has proven benefits for business too.
“Employers can eliminate bias by collecting diversity data during the application process to identify any potential barriers for diverse candidates, including diverse employees on interview panels, and making the recruitment process accessible to everyone so no one gets left behind."
Derek Mackenzie, CEO of Investigo, told HR magazine that employers could eliminate bias by centering people in the recruitment process.
He said: “Recruitment is ultimately about people, so people should be front and centre throughout the hiring process.
“There’s a plethora of ways to eliminate this bias, namely bringing in regular human interaction throughout the process, whether it be curating job descriptions, analysing CVs or contacting candidates for interviews.
“That doesn’t exempt potential human bias, but a representative hiring committee can reduce the potential for AI-driven bias.”
