What Questions Are Not Allowed in a Job Interview

Everyone · Explainer · Updated October 1, 2026 · LearnLife Editorial

What kinds of questions are not allowed in a job interview?

Interview questions that ask about personal traits or characteristics not relevant to the job are prohibited. Employers cannot ask about your race, color, national origin, sex, pregnancy, religion, age, disability, genetic information, marital status, sexual orientation, or citizenship status. For example, questions like “How old are you?” “What country are you from?” or “Do you have children?” are not allowed. These questions can lead to discrimination and violate laws designed to ensure fair hiring. Instead, interviewers should focus on your skills, qualifications, and experience. For instance, rather than asking about childcare arrangements, an employer might say, “Are you able to work the required schedule?” This keeps the conversation job-related and fair.

Illegal questions are often subtle or disguised, such as asking, “What’s your maiden name?” or “Do you have any disabilities?” Knowing which questions are off-limits helps you identify when an interviewer crosses a line. Employers can only ask about personal information when it is absolutely necessary for the job, known as a bona fide occupational qualification. Otherwise, questions must relate strictly to your ability to do the job.

How do these rules work in practice during an interview?

Suppose you are interviewing for a retail position that requires standing for long shifts. A legal question would be, “Are you able to stand for long periods?” This focuses on job duties. An illegal question would be, “Do you have any medical conditions that prevent you from standing all day?” because it probes your health before a job offer. If asked such a question, you could respond, “I am confident I can perform the responsibilities of this role.”

Similarly, asking about marital status or religion is not allowed. For example, “Do you attend religious services?” is off-limits. Instead, the interviewer should say, “This job requires weekend work; are you able to meet that schedule?” This ensures fairness and avoids bias based on personal beliefs.

Employers typically prepare acceptable question lists and train hiring managers to avoid illegal questions. If you face an inappropriate question, you can answer briefly, redirect, or politely decline. For example, if asked, “Are you pregnant or planning to have children?” you might say, “I prefer to focus on my qualifications and how I can contribute to your team.”

Why is it important for job seekers and employers to understand these rules?

Knowing which questions are illegal helps job seekers protect their rights and avoid discrimination. If you recognize an illegal question, you can respond professionally without feeling pressured to disclose personal information. This helps maintain your dignity and can inform your decision about whether this employer values fair treatment.

Employers who follow these rules reduce the risk of complaints, lawsuits, and damage to their reputation. They also create a more inclusive workplace where hiring is based on merit. For example, an interviewer who avoids questions about family status won’t make assumptions about your availability or commitment, leading to fairer evaluations.

Understanding these rules also helps reduce awkward or uncomfortable moments during interviews. It builds trust between candidates and employers, increasing the likelihood of a positive hiring experience.

What are some common interview questions often confused with illegal ones?

Some questions sound personal but are legal if job-related. For example:

• Asking, “Can you lift 50 pounds?” is allowed if the job requires physical strength.
• Asking, “Are you available to work nights or weekends?” is allowed, but not, “What religious holidays do you observe?”
• Asking about criminal history may be legal depending on state laws and only when relevant.

To avoid confusion, focus on whether a question relates directly to the job duties. For example, “Can you operate heavy machinery?” is valid if part of the role, but “Do you have a history of seizures?” is not permitted before a job offer.

Knowing these distinctions helps you answer appropriately and avoid sharing unnecessary personal information.

What should a candidate do if asked an illegal question during an interview?

If an interviewer asks an illegal question, consider these steps:

1. Politely decline to answer. For example, say, “I’m happy to focus on my skills and experience.”
2. Redirect the conversation. Say, “Could you tell me more about the key responsibilities of this role?”
3. Ask how the question relates to the job. For example, “Can you explain how this relates to the position’s requirements?”
4. Make a note of the question and interviewer’s name for future reference.
5. Stay calm and professional throughout.

For example, if asked, “Are you married?” you could respond, “I prefer to discuss my professional qualifications and how I can contribute to the team.” This keeps the interview focused and respectful.

If you feel you’ve been discriminated against, you can contact the Equal Employment Opportunity Commission or a local employment rights office for assistance.

How do state laws and employer policies affect interview question rules?

Federal laws set baseline rules, but many states have stricter regulations. For example, some states prohibit asking about salary history to reduce wage discrimination. Others restrict questions about credit history or criminal records. These laws vary, so it’s important to check your state’s rules before an interview.

Employers may also have stricter policies than the law requires to promote fairness. For instance, a company might prohibit interviewers from asking about family planning, even if not explicitly illegal federally.

Candidates should research both federal and state laws. For example, in some states, employers cannot ask about arrests that did not lead to conviction, or medical marijuana use outside the workplace. Interviewers must be trained on these rules to avoid legal problems and create a respectful hiring environment.

What related terms do people mix up with illegal interview questions?

• Background checks: These happen after the interview or job offer and have separate rules. Interview questions cannot replace background checks.
• Job-relatedness: Questions must relate directly to essential duties. For example, asking if you can lift heavy boxes is valid for warehouse jobs, but probing about health conditions before a job offer is not.
• Reasonable accommodation: Employers can ask if you can perform job duties with or without accommodation but cannot ask about disabilities directly before offering employment.
• Pre-employment inquiries: Tests or medical exams are allowed only after a conditional offer, not during interviews.

Understanding these terms helps you know what to expect and how to respond during the hiring process.

What steps should employers and candidates take next to handle interview questions correctly?

Employers should:

• Develop a list of clear, job-related interview questions.
• Train interviewers on legal and illegal questions with examples.
• Review and update questions to comply with federal and state laws.
• Focus interviews on skills, experience, and job fit.
• Avoid questions about personal life or protected characteristics.

Candidates should:

• Prepare answers to common, legal interview questions.
• Learn which questions are illegal and plan polite responses.
• Practice redirecting or declining inappropriate questions.
• Know their rights and where to get help, such as the EEOC.
• Keep notes if they experience questionable interview behavior.

For example, you might prepare to say, “I’m happy to discuss how my experience meets the requirements of this position,” to keep the interview focused on your qualifications.
