Illegal interview questions
There are questions employers should not ask. In fact, federal and state laws prohibit prospective employers from asking certain questions that are not related to the job they are hiring for. Questions should be job-related and not used to find out personal information.
In a nutshell, employers should not be asking about your race, gender, religion, marital status, age, disabilities, ethnic background, country of origin, sexual preferences or age.
If you are asked illegal questions you have several options. You can simply answering the question. You can answer the intent of the question. For example, if you are asked whether you are a United States citizen, you can reply that you are authorized to work in the U.S. (which is all they legally need to know). You can change the topic of conversation, and perhaps the interviewer will even realize their misstep, or you can refuse to answer the question all together.
