You're sitting across from a promising candidate. The conversation is flowing naturally. They mention their kids, and before you think twice, you ask, "Oh, how old are they?"
Harmless small talk? Maybe. But in an interview context, you just opened a door that could lead to a discrimination claim.
Most business owners who ask illegal interview questions don't do it maliciously. They do it because the line between friendly conversation and compliance risk isn't always obvious. This guide makes it clear.
Federal anti-discrimination laws - enforced by the Equal Employment Opportunity Commission (EEOC) - prohibit employers from making hiring decisions based on protected characteristics. These include race, color, national origin, sex (including pregnancy and gender identity), religion, age (40 and older), disability, genetic information, and marital or family status.
The rule is simple: if a question relates to a protected characteristic and isn't directly relevant to the candidate's ability to perform the job, don't ask it.
About Age: Don't ask "How old are you?" or "When did you graduate?" Instead, ask "Are you at least 18 years of age?" (if relevant to the role) or "Do you meet the minimum experience requirements listed in the job description?"
About Family and Marital Status: Don't ask "Are you married?", "Do you have kids?", or "Are you planning to start a family?" Instead, ask "Are you able to meet the attendance and schedule requirements for this position?" or "This role requires occasional travel - is that something you can accommodate?"
About National Origin: Don't ask "Where are you from?" or "What's your native language?" Instead, ask "Are you authorized to work in the United States?" or "Are you fluent in any languages required for this role?" (only if relevant to the position).
About Religion: Don't ask "Do you go to church?" or "What religious holidays do you observe?" Instead, ask "This position requires Saturday availability - are you able to work on Saturdays?" (only if the schedule is a genuine requirement).
About Disability: Don't ask "Do you have any disabilities?" or "How's your health?" Instead, ask "Are you able to perform the essential functions of this position, with or without reasonable accommodation?"
About Pregnancy: Don't ask "Are you pregnant?" or "Are you planning to have children soon?" There is no compliant alternative for this question - it's simply not relevant to someone's ability to do the job.
About Arrest History: Don't ask "Have you ever been arrested?" In many jurisdictions, you can ask "Have you ever been convicted of a crime?" - but timing matters. Many states and cities have "ban the box" laws that prohibit asking this question until after a conditional offer has been made.
Before you ask any question, run it through this filter: "Does this question directly relate to the candidate's ability to perform the essential functions of this job?"
If the answer is yes, it's likely fine. If the answer is no - or if you're not sure - don't ask it.
What If a Candidate Volunteers Information?
Sometimes candidates will bring up protected information on their own. They might mention their age, their kids, or their religion in casual conversation.
Here's what to do: acknowledge it politely, then steer the conversation back to job-related topics. Don't write the information down. Don't ask follow-up questions about it. And don't let it factor into your hiring decision.
If it comes up in your notes or debrief with other interviewers, it creates a paper trail that could be used against you in a discrimination claim - even if the information had nothing to do with your decision.
If anyone at your company participates in interviews - managers, team leads, peers - they need to know these rules. One well-meaning but illegal question from a panel member can create liability for the entire organization.
A 15-minute training session can save you from a six-figure lawsuit.
Great interviews are structured, consistent, and fair. They focus on skills, experience, and fit for the role - not personal details that have nothing to do with someone's ability to do great work.
