When conducting a job interview, don't inject gender, race, age or religion, and don't respond to questions or comments treading into those topics.
Innocent exchanges can be legal pitfalls.
Each state may have additional laws. Title VII forbids employers from discriminating against people with respect to employment, from depriving people of employment opportunities and from otherwise adversely affecting a person's status as an employee because of his or her race, color, religion, sex or national origin. At its most basic level, Title VII forbids businesses from consciously deciding not to hire, promote or retain people based on race, religion, sex, national origin or age. This is different from the case where a business person consciously decides to discriminate based on race, religion, etc. Take, for example, a business that will not hire anyone lacking a college degree.
