Illegal Interview Questions

Illegal interview questions are questions that an employer is not allowed to ask a potential candidate during the interview or within the interview process.

These questions should be avoided and should not be asked under any circumstances.

The law provides candidates with some degrees of protection and discrimination.

You can review our write-up on discrimination and what to do if you feel like you’ve been fired illegally here.

However, from an employer’s perspective, you need to be extra careful to not ask questions which are illegal.

Asking these questions can prompt a lawsuit and you could jeopardize your career.

When interviewing a candidate, regardless of position, you should focus on their experience and their qualifications.

Always ask questions related to their previous work history and their education.

Don’t veer into personal questions or sensitive topics.

Such questions are not only illegal, but they don’t help to further the needs of your department.
