How to respond in a HV way when LV men ask you about your weaknesses and insecurities?

Hi, I have gotten this rude question a few times in different ways, but there are several ways that it plays out. If I joke that I don't have any weaknesses, or a lady doesn't tell, they usually persist. If I answer a light weakness like being lazy or being impatient, but describe a way that I'm working on it, they usually insist that there must be something worse than that. I'm not going to be stupid and answer anything else.

A few friends suggested that I just joke "are we doing a job interview?", Or just answer that I don't feel comfortable answering, but just wondering whether there is anything better.

Thank you, ladies
