A plain-English guide for the business owners and managers evaluating HireGuard. What the work-style check measures, how a candidate takes it, why the evidence behind it is sound — and, just as importantly, what it deliberately is not.
A short (≈5-minute), science-based work-style check — taken on a phone, alongside the HireGuard video interview — that gives you a role-fit read on a candidate, so you hire the right person the first time. It's decision support, never the decision.
Hiring the wrong person is expensive, and in the UK it's getting harder to undo — the Employment Rights Act 2025 moves unfair-dismissal protection towards day one. The sensible response isn't to fire faster; it's to choose better up front.
Most small employers hire on a CV and a gut-feel chat — the two weakest predictors there are. The work-style check adds a structured, consistent, evidence-based signal to the same short process, at no extra effort for you.
Decades of peer-reviewed research point to a handful of traits that predict service and frontline performance — and, importantly, a blend of them researchers call service orientation.
Dependability — reliability, follow-through, and getting things done. The trait that most consistently predicts performance across almost every job.
People-focus — warmth, cooperation and handling customers well. It carries far more weight in customer-facing roles than in solo ones.
Emotional stability — staying steady with difficult customers and busy shifts, rather than rattling under the inevitable pressure of frontline work.
We weight these the way the evidence says to for the role you're hiring for, add a few "what would you do?" scenarios (a short situational-judgement set), and turn it into a single, plain-English role-fit read that sits next to the candidate's interview score.
A candidate gets a link — or it's bundled into the HireGuard video-interview invite. Nothing for you to set up per candidate.
Around 30–40 quick questions — no camera, no account, no download.
A headline "service score" for customer-facing roles, plus the two or three traits that matter for that job, each explained in one line.
It sits next to the spec-scored video interview and everything you already know — as one input to your decision.
It's built on public, validated science; it's weighted to the traits and the service blend that research links to frontline performance; it has low adverse impact versus aptitude testing; and it's advisory decision-support.
That it "predicts" any individual's success. The science is real but modest and group-level — it shifts the odds in your favour across many hires; it is not a crystal ball for one person. And because it's self-report, a determined candidate can flatter themselves — so we keep it advisory, cross-check it against the interview, and never let a single score decide anything.
The best modern evidence (Sackett, Zhang, Berry & Lievens, 2022, Journal of Applied Psychology) shows that structured interviews and well-chosen personality measures are among the most useful, fairest selection tools — and that the famous "just test IQ" advice was based on overstated older numbers. For customer-facing work specifically, a blend of conscientiousness, agreeableness and emotional stability predicts performance about twice as well as any single trait (Frei & McDaniel, 1998), with little of the demographic bias that aptitude tests carry. That's the instrument we built — nothing more, nothing less.
The full evidence base, methodology and the contested points are kept in our companion Validity Manual; the design spec sits in our hiring-psychometric notes. We update the claims on this page if the evidence moves.
