Half Your Interviewers Might Be Breaking the Law Without Realizing It

Here's an uncomfortable one: according to Greenhouse's 2025 Workforce and Hiring Report, 53% of U.S. job seekers say they've been asked an illegal or discriminatory interview question. Not "an awkward question." Illegal.

The most common offenders:

— Age — 31% of job seekers were asked about it

— Health or disability status — 22%

— Physical appearance — 22%

That's not a handful of rogue hiring managers going off-script. At those rates, this is a structural problem — the natural result of interviews that run on gut feel, small talk, and whatever question happens to come to mind under time pressure.

The instinct is to blame the interviewer. Send everyone to a bias-awareness workshop, tell them what not to ask, move on. It helps a little — and it's nowhere near enough on its own, because the underlying process is still improvised. Give ten hiring managers a blank slate and a resume, and you'll get ten different interviews, with ten different chances for an off-limits question to slip out.

The more durable fix is structural: structured hiring. Define the role's actual criteria before you source a single candidate. Write the interview questions in advance, tie them to that criteria, and ask every candidate the same ones. Score answers against a shared rubric instead of a vibe.

That one shift does several things at once:

— It closes the improvisation gap. If the questions are written down and approved before the first interview happens, there's no moment where an interviewer is reaching for something to ask and lands on age or health status.

— It widens the funnel. Skills-based, role-relevant criteria — instead of pedigree or "culture fit" read off a gut feeling — let qualified candidates from underrepresented backgrounds advance further, because the things working against them (a school name, an accent, a gap in a resume) simply aren't on the scorecard.

— It creates a paper trail. Decisions tied to documented, job-relevant criteria are defensible if a hiring decision is ever challenged — and just as usefully, they let you go back and see where in the process good candidates are falling out, instead of guessing.

Structured hiring isn't a philosophy, it's a checklist:

Write down what the role actually requires before you post it — not a wish list, the real must-haves.

Turn those requirements into a fixed set of interview questions, agreed on by the hiring team in advance.

Build a scorecard that rates every candidate against the same criteria, not against each other's vibe.

Ask every candidate the same core questions, in roughly the same way.

Score right after each interview, before the next candidate resets your impression.

Review the pattern across candidates, not just the individual scores — that's where bias hides.

None of this requires new headcount or new software. It requires deciding, before the first interview, what "qualified" actually means for this specific role — and then not letting the conversation wander past it.

A 53% rate of illegal interview questions isn't a training problem, it's a design problem. Fix the design — structure the process before the people run it — and the bad questions mostly stop asking themselves.
