An interviewer asked an illegal question: what the recruiter should do next

Treat it as a process problem to contain, not a mistake to bury. The same day, get the exact question and answer in writing, tell everyone involved in the decision not to consider the answer, and hold the decision until you know whether that interviewer's scores can stand. Keep every record (federal rules require it), move any medical or genetic information into a confidential file, decide whether a different interviewer should repeat the stage, coach the interviewer, and agree with HR or counsel what to tell the candidate. This summarizes federal rules as of October 2026 and is not legal advice.

Illegal interview questions covers what not to ask and what the interviewer should say in the moment. This page is for the next person in the chain: the recruiter or HR partner who hears about it afterwards, from the interviewer, another panelist, the notes or the candidate.

What should the recruiter do in the first 24 hours?

1. Get the facts in writing. Ask the interviewer, and anyone else on the call, for the exact words of the question, what led to it, whether the candidate answered, what they said, and where it was written down: notes, scorecard, chat, an AI note taker's transcript or summary, messages to colleagues.
2. Classify the question using the table below. Some questions break a rule the moment they are asked; others create risk only if the answer influences the decision.
3. Tell the decision-makers, in writing, not to consider the answer. Name the competencies affected. Do not repeat the answer in that message.
4. Hold the decision for this candidate until you have decided whether the evaluation can stand. A rejection sent the day after the question will be read as connected to it.
5. Separate, do not delete. Add a dated note to the file saying what was asked and that the answer is excluded. Move medical or genetic details into a confidential file (see the records section).
6. Bring in HR or employment counsel if the candidate has complained, if the question touched disability or family medical history, or if the same interviewer has done it before.
7. Decide on the stage, the interviewer and the candidate, using the sections below.

Is the question itself unlawful, or only risky?

Federal law treats questions differently. For disability and genetic information, asking is itself prohibited. For most other protected characteristics, the U.S. Equal Employment Opportunity Commission (EEOC) says on its prohibited practices page that federal law does "not clearly forbid" such inquiries, but they "may be used as evidence of an employer's intent to discriminate unless the questions asked can be justified by some business purpose."

Federal anti-discrimination laws apply to employers above a size threshold: 15 employees for most of them and 20 for age, according to the EEOC's small business guidance. State laws often reach smaller employers. The illegal interview questions page lists the thresholds and the main state and city additions.

Should another interviewer redo that stage?

Decide on what the evidence shows about contamination, not on how uncomfortable the conversation was:

A repeated stage must use the same questions and anchors every other candidate had, or the comparison breaks for a different reason. Offer the repeat, do not require it, and schedule it quickly; the candidate did nothing wrong and should not lose their place because of it. Independent scorecards, submitted before any discussion, make this decision much easier, because you can see what the interviewer wrote before anyone else's opinion reached them.

Which records must you keep, and where?

• Keep everything. 29 CFR 1602.14 requires employers covered by Title VII, the ADA and GINA to keep hiring records for one year from the date they were made or the decision was taken, whichever is later. Once a charge is filed, everything relevant must be kept until final disposition, including the application materials of the other candidates for the same position.
• Exclude rather than erase. A dated note on the file ("Answer to [topic] question excluded from evaluation on [date] by [name]") is the record that shows what you did. Deleting the answer removes the proof that it was excluded.
• Move medical and genetic information. GINA's rule requires written genetic information to be kept on forms and in medical files separate from personnel files, treated as a confidential medical record (29 CFR 1635.9). Treat health details a candidate disclosed in the same way: in a restricted file, not the hiring record everyone can read.
• Include machine records. If the interview was recorded or transcribed, the recording, transcript and any AI summary are records too. Restrict access to the passage; do not edit the transcript.
• Write your own account the same day: who reported it, what you were told, what you did and when. If a charge arrives months later, this is the document you will want; see what to do about an EEOC charge from a rejected candidate.

What should never have been written down in the first place is covered in what not to write in interview notes.

What should you say to the candidate?

If the candidate raises it, reply within a day or two, in writing or by phone with a written follow-up. A reply that works:

Hi [name],

Thank you for telling me about the question you were asked in your
interview on [date]. It should not have been asked. Your answer will
not be considered in any part of our decision, and I have made sure
the people involved know that.

[If you are offering a repeat: We would like to offer you a
conversation with a different interviewer covering the same topics,
at a time that suits you.]

Your application is continuing as normal. If you have any other
concerns, please contact me directly at [phone or email].

[name]

What not to say or do:

• Do not explain or defend the interviewer's intent ("he was just making conversation"). It invites an argument about the very thing you are trying to take out of the process.
• Do not repeat or discuss the candidate's answer.
• Do not promise an outcome, and do not ask them to sign anything or keep the matter confidential.
• Do not pause, slow down or reroute their application because they complained. Title VII makes it unlawful to discriminate against "employees or applicants for employment" because they opposed an unlawful employment practice or took part in a charge (42 U.S.C. 2000e-3(a)).

If the candidate did not raise it, agree with HR whether to say anything. If you offer a repeat stage, give a true reason, such as "we want a second interviewer's view on the same topics", without disclosing more than you need to. When the eventual decision is a no, the rejection should rest on documented, job-related evidence, and the message to the candidate should say nothing about the question or their answer.

How should you coach the interviewer?

For a first slip that was reported promptly, coaching works better than discipline, and it keeps people reporting slips rather than hiding them. Cover four things in a short private conversation:

1. Why the question matters, in the terms above: either it is prohibited outright, or the answer becomes evidence about the decision.
2. What triggered it. Most slips happen in small talk at the start or the end. Agree what they will talk about instead (the role, the team, the candidate's questions).
3. The lawful version of what they wanted to know, for example "This role travels two nights a month. Can you meet that?" instead of a question about children.
4. What to do next time: stop, say the candidate does not need to answer, write nothing down, and tell the recruiter the same day.

Record that the conversation happened. A second slip, a question asked on purpose, or a question about disability or family medical history goes to HR under your normal process. The interviewer code of conduct template makes this expectation explicit before the next loop, including the rule that reporting a slip promptly is what you want people to do.

What if the interviewer works for your agency's client?

Agency recruiters often hear about it first, from the candidate after a client interview. Write down what the candidate told you, in their words, and tell your client contact in writing that the question was asked and that you expect the answer to be excluded from the decision. Do not pass the candidate's answer on to anyone. The EEOC's guidance on staffing firms (1997) says that when a client discriminates against workers a staffing firm places, and the firm knows or should know, the firm must take corrective action within its control. That guidance speaks of workers the firm assigns; for a direct-hire submittal, treat it as the standard to work to and involve your own counsel if the client refuses to act.
