There are some questions that are illegal for a hiring manager to ask you, such as age, or other personal questions like sexual preference or religion. It’s best to do some research on these questions before you go into the interview. If a manager asks one of these questions, it’s best to dodge the question and decide later whether it’s a red flag or if it seemed to be asked out of innocent ignorance rather than malice. Don’t forget, you’re not just getting interviewed by an employer – this is your chance to interview an employer too, and determine if they’re the right fit for you.
