Definition
Hiring signal — A hiring signal is any concrete piece of evidence a recruiter or hiring system uses to evaluate a candidate's fit for a role. Signals range widely in what they measure: a school name or a previous employer's brand is a proxy signal, weakly correlated at best with how someone will perform in a new role; a specific answer to a technical question, evaluated on its own merits, is a much more direct signal of relevant skill. Traditional hiring has leaned on proxy signals, resume items like job titles, tenure, and pedigree, partly because they're cheap to collect and partly because gathering direct evidence, like watching someone perform a task, takes more time per candidate. The distinction matters because a process built mostly on proxy signals can miss strong candidates whose direct evidence would tell a very different story.
The push toward stronger hiring signals is part of why structured interviews, scored assessments, and work samples have grown as a category: they generate direct evidence about a specific skill rather than relying on a loose proxy. The tradeoff is usually cost, since collecting direct evidence for every applicant, not just a shortlisted few, was historically expensive to do manually.
The Intervieux angle
Intervieux treats the AI interview itself as the primary hiring signal rather than a formality layered on top of a resume. Every AI interview produces five scored dimensions with written reasoning, generated directly from a candidate's actual spoken responses, giving employers direct evidence at the scale a resume-only process can't reach.
Frequently asked questions
Is a resume a weak hiring signal?
It's a proxy signal, meaning it correlates with performance in some cases but doesn't directly demonstrate a candidate's actual skill. A resume line about job title or tenure says less than a scored answer to a specific relevant question.
Why do direct hiring signals cost more to collect than proxy signals?
Direct evidence, like a scored technical response, traditionally required a person's time to generate and evaluate for each candidate, while a resume line is already there to scan in seconds.
Can AI make direct hiring signals cheaper to collect at scale?
That's the underlying promise of AI screening and interview scoring, generating and evaluating direct evidence, like a real interview response, for every applicant rather than only a small shortlisted group, without the per-candidate cost a fully manual process requires.
