What is an illegal Question?

Illegal interview questions refer to those questions asked during an interview that may be used to discriminate against an interviewee. It is important to be aware of what questions are illegal before you start an interview. In most cases, personal questions not related to job performance can be illegal interview questions, as they can be used to discriminate on the basis of a person's age, place of origin, birth place, etc.

If a candidate does not answer any illegal interview questions, you should not hold it against him, because it is his right.

And remember: The act of asking these questions is not illegal. But to reject someone on the basis of the answers provided is illegal. It could expose you to a possible law suit if the applicant is rejected and feels that it was due to that issue.

Personal Questions

National Origin/Ancestry


Unlawful Inquiries: Everything. "What is your nationality?", "How did you acquire the ability to speak, read or write a foreign language?", "How did you acquire familiarity with a foreign country?", "What language is spoken in your home?", "What is your mother tongue?"

Lawful Inquiries: "What languages do you speak, read or write fluently". This is only legal when the inquiry is based on a job requirement.

And remember this...

The questions do not necessarily have to be asked in a direct fashion to be illegal interview questions.

Some questions may be illegal based on the reason they were asked.

For example it is legal to ask if the applicant is fluent in another language if it is relevant to the job.

However it should not be asked if it is not relevant to the job and is used to gain information about a person's nationality or place of birth.

Avoiding illegal interview questions avoid the chances of a candidate being discriminated against. Also it can save you from possible law suits.
