As always, whether or not any particular interview question is lawful or unlawful (as discussed below) will depend on whether or not you’re covered by a law that prohibits the question from being asked.
Similarly, just because a question can be asked during an interview does not mean that it should be asked! As a general rule, all interview questions should concern the applicant’s ability to perform the duties of the job in question. Obviously, ensuring that the employee is a good fit for your organization is also important, but should not be the focus of the interview process. Questions regarding “fit” can be asked, but you should give careful consideration to the question you will ask regarding all subjective job qualifications.
