I know it’s technically illegal for interviewers to ask if you have kids and discriminate but as a women I have been asked every single time if I have kids or plan to. And it’s always asked kinda in like a small talk way not like it’s one of the interview questions but let’s be real it affects their opinion. I’m 29 married and don’t have kids so I always just say nope no kids cause I figured it works in my favor since it makes me seem more reliable. But if I didn’t want to answer the question what’s a polite way of declining to answer without seeming rude or unprofessional?
