Interviewing candidates can feel like an awkward first date. Sure, you’re asking all the right questions about what you’re looking for, but you’re also just having a casual chat with someone cool—right?
In the world of interviews, that’s not totally the case.
During the conversation, you have to strike a balance between wanting to make your candidate feel at ease without slipping into dicey question territory. Or in other words asking them illegal interview questions.
And what may feel like innocuous chatter could actually balloon into giant HR no-nos, giving the person grounds to say they were discriminated against. In fact, CareerBuilder found that 20 percent of hiring managers admit to having asked an illegal interview question at some point in their life (which they only realized after the words left their lips).
But with a little understanding of what’s really off limits, you won’t have to freak out.
Below are some questions to steer clear of — along with a few reworded alternatives you can happily pack into your interview backpack.
Age
Thanks to the magic of math, this question is surprisingly easy to bring up without directly asking it outright.
While you do have a right to know if the person you’re interviewing is 18 or older, that’s basically the end of it. The Age Discrimination in Employment Act of 1967 bars employers from discriminating against people 40 or older, so trying to chip away at the answer can land you in hot water.
Not to mention, a lot of states also have measures in place to prevent age discrimination for those who are younger than 40. It really doesn’t matter what direction the age questions go—just don’t do it.

Questions you can ask
Family and living situation
Usually, asking about someone’s personal life is a surefire way to speed up the getting-to-know-you process.
Unfortunately, a lot of these questions can easily slip into pregnancy and gender discrimination territory, which are protected classes under laws enforced by the Equal Employment Opportunity Commission.
For example, if you know a candidate has kids, they can argue that it prevented them from getting the role because they may have been seen as less available than someone who was child-free.

Nationality and ethnicity
Any question that tries to deduce someone’s national origin or ethnic background is completely off limits.
Even asking about things that seem harmless, like what languages a person speaks, can be seen as a way to triangulate where they’re from.
Questions you shouldn’t ask
*This question should generally be avoided, but if the job requires proficiency in a certain language, you can ask whether the candidate is proficient in that language, as described below.
Questions you can ask
Religious background
Some employers unknowingly veer into the religion realm because they want to know how available the person will be during the holidays. Candidates don’t have to reveal any of that information to you, along with any religious or non-religious organizations they’re a part of.
However, you can snap up the information you need without having to bring up religion.

The top taboo questions are now right in front of you. With this list of illegal interview questions, you’ll be better prepared to step into any interview room and make those butterflies disappear.
All you have to do is dial into what you really want to know about your knockout candidate—without knocking into any weird HR stickiness along the way.
