What Employers Can and Cannot Legally Ask You in a Job Interview
Federal law draws clear lines around age, race, disability, and family status, but the real liability for employers often hides in questions that sound harmless: small talk about graduation dates, weekend availability, or salary history.
A job interview question becomes illegal not because of the words used, but because of what it reveals or what it could be used for.

Employers cannot ask about race, age, disability, national origin, religion, marital status, or pregnancy, whether directly or through indirect framing such as asking about high school graduation year or childcare arrangements.
They can ask about qualifications, availability, work history, and job-related capabilities. The line is drawn by federal law, but the details shift by state.
Most articles on this subject list the obvious categories: no questions about age, no questions about religion, no questions about family plans. That list is accurate but incomplete, and incomplete lists are exactly what get employers in trouble.
The real risk sits in the gray areas: the “innocent” small-talk question that doubles as a proxy for a protected trait, the state law that overrides what federal law allows, and the well-meaning interviewer who thinks empathy justifies asking about a candidate’s health.
The Legal Framework Behind the Rules
Three federal statutes do most of the work here. Title VII of the Civil Rights Act of 1964 bars discrimination based on race, color, religion, sex, and national origin. The Age Discrimination in Employment Act (ADEA) protects applicants aged 40 and over.
The Americans with Disabilities Act (ADA) prohibits discrimination against qualified individuals with disabilities and restricts what medical or disability-related questions can be asked before a job offer is made. The Genetic Information Nondiscrimination Act (GINA) adds a narrower but frequently overlooked layer, barring employers from asking about family medical history or genetic test results.
The Equal Employment Opportunity Commission (EEOC) enforces these laws and defines illegal discrimination as treating someone unfavorably because of race, color, religion, sex, national origin, age of 40 or older, disability, or genetic information.
None of these statutes contains a literal list of banned interview questions. Instead, they prohibit discrimination based on outcome and intent, and a question about a protected category is treated as evidence that intent existed, regardless of whether the employer ever used the answer to make a decision.
That distinction matters more than most hiring managers realize: asking “How old are you?” and not hiring the candidate for unrelated reasons still creates exposure, because the question itself becomes exhibit A in a discrimination complaint.
The regulatory environment shifted meaningfully in 2026. On June 30, 2026, the EEOC officially rescinded two longstanding documents relating to permissible affirmative action guidance under Title VII, and the agency has been operating under a new enforcement roadmap that sets national priorities running from mid-2026 through fiscal year 2029.
Employers building interview training around guidance that predates these changes are working from an outdated playbook.
The Categories Employers Cannot Touch
Age
Federal law protects applicants aged 40 and older from age-based discrimination, but the practical risk zone is broader than the statute’s floor suggests. Direct questions like “What year did you graduate high school?” function as a proxy for age even though the word “age” never appears, and this is precisely the kind of indirect questioning that plaintiff’s attorneys look for first.
Employers can confirm that a candidate meets a legal minimum age requirement for a specific role, such as serving alcohol, but cannot use graduation dates, birth years, or “how many more years until retirement” framing to extract the same information under cover of small talk.
Family Status, Marital Status, and Pregnancy
Questions about marital status, childcare arrangements, or pregnancy plans remain among the most frequently cited violations, and the EEOC has advised that these questions, including questions about childcare arrangements, are often used to discriminate against women in violation of Title VII.
The mistake employers make here is assuming that asking every candidate the same question, regardless of gender, provides legal cover. It does not. Even when a question about family status is asked of every applicant, it can still be viewed as evidence of intent to discriminate against a protected group.
The Pregnant Workers Fairness Act, which took effect in 2023, adds a further layer by requiring reasonable accommodation for pregnancy-related conditions, which means employers should be actively avoiding pregnancy-adjacent questions rather than treating the ADA and PWFA as someone else’s problem.
National Origin and Citizenship
Employers can ask whether a candidate is authorized to work in the United States, but cannot ask about citizenship status, birthplace, or nationality. The distinction is subtle and frequently mishandled: “Are you authorized to work in the U.S.?” is a lawful, job-related question because it maps directly onto a legitimate business requirement (I-9 compliance).
“Where are you from?” or “Is English your first language?” does not map onto any legitimate business need and instead functions as a proxy for national origin, which is a protected category under Title VII.
Disability and Health
The ADA restricts medical inquiries in a way that trips up even well-intentioned interviewers. Before extending a conditional offer, employers cannot ask whether a candidate has a disability, has ever filed a workers’ compensation claim, takes prescription medication, or has a chronic illness.
What employers can ask, and what many fail to ask because they conflate it with the illegal version, is whether the candidate can perform the essential functions of the job, with or without reasonable accommodation.
That reframe, from “Do you have a disability?” to “Can you perform these specific job duties?”, is the single most useful rewrite in disability-related interviewing and the one most compliance training glosses over.
Religion
Employers cannot ask about religious affiliation, observed holidays, or houses of worship attended. Where this becomes genuinely difficult is scheduling: an employer legitimately needs to know if a candidate can work the shifts the role requires, but framing that as “Can you work Saturdays?” risks functioning as a religious-observance filter if it is asked selectively or if the underlying motive is to screen out Sabbath-observant candidates.
The defensible version asks about availability for the specific shift pattern the job requires, applied uniformly to every candidate for that role, without referencing why the candidate might or might not be available.
Criminal History
This is where federal permissiveness and state restriction diverge sharply. Federal law does not prohibit employers from asking about criminal history, but that information cannot be used to discriminate, and depending on state or local law, some jurisdictions do not allow the use of arrest and conviction records to disqualify a candidate from employment.
The “ban the box” movement, now adopted in some form across a majority of states and dozens of cities, removes the criminal-history checkbox from job applications and generally prohibits asking about arrest and conviction records until later in the hiring process, unless the conviction is directly related to the job, such as a record involving violence against children for a role working with minors. The EEOC’s own recommendation is that employers avoid asking about convictions on the initial application and wait until after a conditional offer has been made.
A subtler distinction that most articles collapse into one rule: arrest records and conviction records are not treated the same way legally. The EEOC has noted that because certain minority groups are statistically arrested more often than others, questions about arrest records specifically, as opposed to convictions, carry elevated risk of functioning as a proxy for racial discrimination.
An arrest without conviction reflects an accusation, not an adjudicated fact, which is why several jurisdictions treat bare arrest records as categorically off-limits even where conviction history can eventually be considered.
Genetic Information
GINA is the least discussed of the major federal statutes but carries real teeth. Employers cannot ask about family medical history, results of genetic testing, or whether relatives have specific hereditary conditions. This surfaces most often in casual wellness-program small talk rather than formal interviews, but the same prohibition applies during hiring.
The Gray Zones Where Most Real Risk Lives
The categories above are the ones training programs cover well. The following are the ones that generate actual EEOC complaints, because they look neutral on their face.
Salary history. Employers should not ask job applicants about salary history before verifying that the question is legally permissible in their jurisdiction.
This is no longer a minor compliance footnote. Eighteen states, including California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Nevada, New Jersey, New York, Oregon, Rhode Island, Vermont, Virginia, and Washington, along with the District of Columbia, now ban salary-history questions statewide, with Virginia’s law taking effect July 1, 2026. Dozens of additional cities and counties layer on their own versions.
The practical implication for any employer hiring across state lines: build a policy that never asks about pay history anywhere, rather than trying to maintain a jurisdiction-by-jurisdiction exception map that a hiring manager will inevitably get wrong.
Availability questions. Availability questions are not inherently illegal according to the EEOC, but they can become illegal if used to discriminate, such as asking whether a candidate can work weekends in a way that could function as a religion proxy, or asking whether a candidate can work nights only of women applicants. The question itself is neutral; the pattern of who it gets asked to is where liability attaches.
Emergency contacts and military discharge type. Neither is on the EEOC’s list of prohibited questions, but emergency contact information should not be collected until after hire, since it can reveal marital or family status, and questions about the type of military discharge received are generally avoided because they can surface disability-related or other sensitive information indirectly.
Weight and unemployment status. These sit in a genuine gray area that varies more by local ordinance than by federal statute, and a small number of jurisdictions specifically bar discrimination based on current unemployment status, treating it as a proxy for age or economic hardship.
What Employers Can Legally Ask
The legally safe version of nearly every risky question exists; it just requires anchoring to the job rather than the person. Employers can ask about relevant work experience, specific technical skills, professional certifications, willingness to travel for the role, availability for the specific shift pattern required, salary expectations (as distinct from salary history), reasons for leaving previous roles, and, after a conditional offer, results of a job-related background check.
The reliable rule of thumb across virtually every HR compliance resource is to stay away from anything not directly related to the job, resist the pull toward personal conversation, and avoid asking about anything that can be learned another way.
A Framework for Evaluating Any Interview Question
Rather than memorizing an exhaustive list of banned topics, which will always miss an edge case, run each planned question through three filters before it reaches a candidate:
Does the answer map to a protected category, even indirectly? Graduation year maps to age. Maiden name maps to marital status. Accent-related questions map to national origin.
Is there a job-related version of the same underlying concern? Instead of “Do you have kids?”, ask “This role requires occasional weekend travel with two weeks’ notice; is that workable for you?” The second version extracts the operationally relevant information without the legal exposure of the first.
Would this question be asked identically of every candidate, regardless of their apparent race, gender, age, or background? Uniform application does not eliminate liability entirely, as the family-status case law shows, but non-uniform application is close to a guaranteed loss if a complaint is filed.
What to Do If You’re Asked an Illegal Question as a Candidate
Candidates are not required to answer, and refusing to answer is not itself a red flag employers can act on.
The pragmatic options, in order of confrontation: redirect toward the job-related concern the question is probably fishing for (“If you’re asking about my availability for travel, I’m flexible with two weeks’ notice”); decline politely and note that the question isn’t one that relates to the role; or, if the pattern continues or the question is used against a hiring outcome, file a complaint with the relevant EEOC field office. Documentation matters here as much as it does for employers: dates, exact wording, and who was present.
The Compliance Mistake That Recurs Most Often
The most common failure isn’t a rogue interviewer asking something obviously illegal. It’s the absence of a structured interview process in which every candidate for a role is asked the same set of pre-vetted, job-related questions and scored against the same rubric.
Without that structure, an employer facing an EEOC complaint is relying on scattered notes and an interviewer’s memory of a conversation from months earlier, which does not hold up under investigative scrutiny. Structured interviewing does two things simultaneously: it removes the improvisational moments where illegal questions tend to slip out, and it gives the employer a defensible paper trail if a complaint is ever filed.
EEOC enforcement data for fiscal year 2023 alone shows roughly $665 million in monetary relief for more than 22,000 charging parties, a figure that makes clear this is not a theoretical risk category reserved for negligent employers; it is an active and well-funded enforcement area.
The safest interview, for both sides, is one built entirely around a single question: does this tell the employer something about the candidate’s ability to do the job? Everything that fails that test is either unnecessary or illegal, and often both.
