Not sure if it's a pattern but when I interviewed with an EU company recently, they explicitly asked if I was married and if I had kids. They explained it as they had a "European mindset towards weekends and holidays" and they expected me to NOT be online.
I was fine with the mindset but never expected to get those questions in an interview, as it'd be illegal in the States.
To be clear: the question isn't illegal. What is illegal is using it to discriminate against a protected class, so as a result, no interviewer with half a brain will ask those questions.
