I always thought employers weren't legally allowed to ask you about having children in an interview, as it could be interpreted as being discriminatory.
However, I was recently asked if I planned to have any more children in a second round interview by a senior manager. I already have 2 DC, which is clear from my CV, and it had already come up in the conversation anyway. In response I just made a joke about having enough already, but was quite shocked that he actually asked the question.
Is this quite common then? Never happened to me before (though have had suggestions about how long nights at work don't mix with childcare - genius).
What would you say in a similar situation? I'd would have like to have said something like "Do you ask all your male applicants that question as well?", but the coward that I am, just kept my mouth shut. Do you have a witty come-back in your arsenal that does not ruin your chances of actually securing the job?
