There are some workers that would relocate with the whole family.

This means the significant other has to find a job and fit it, kids have to go to school.

While many countries have a very decent proficiency in English, you're whole family must fully invest in learning the local language. And that in addition to using English in the office of at least one of the adults (since many big companies use English officially)

Like e.g. Berlin, the large Dutch cities are very much internationally-oriented and usually it's not problem to get a job and integrate if you don't speak Dutch. Sometimes the issue is quite the opposite -- my wife wanted to learn Dutch, but people would just switch to English or German and she would have to ask them explicitly to speak Dutch.

Kids pick up other languages in no time. A lot of friends/colleagues moved between countries (academia) and the kids would usually pick up a language in 2-3 months. I have lived in Australia for six months when I was four. When we returned, I spoke English with an aussie accent (though that's gone now ;)).

Living in Berlin if you don't speak German you are limited in employment, in healthcare, and possibly socially depending on your bubbles. Short time you may not notice it but long term you are probably best learning German. A friend of mine is struggling to find a job right now and lack of German is a big problem for them. Another friend started dating someone who's not herself in the anglophone tech bubble and can't hang out with her friends. Have translated for a friend in hospital for a operation.

Some people can deal with this, even long term, but it's definitely not for me.
