Wolters Kluwer Project Manager interview questions

Very good product management questions. How do you a survey a product; pricing decisions, market analysis.

I have never been asked this - and this question should never be asked - but the hiring manager asked me if I had kids. He did it casually and I delayed answering the question. He then persisted by saying 'I would say you have, what, 2 or 3 kids.' I reluctantly answered. Damned if if you damned if you don't. He went on to say he had two kids. There is not reason this question would be asked unless he was worried I wouldn't be able to tdo my job because I had kids. Would he have asked a male candidate that?
