In general, when applying for a job in Europe, you're expected to submit a CV (curriculum vitae), as opposed to a simple resume that most American companies expect.
Until now, I've never been in a situation where I've needed to write up a CV, so I've been asking around for some advice. There are some basic differences that I was already pretty clear on, like including more thorough detail in job descriptions and education, as well as some details about hobbies and interests.
I also learned, however, that Danish employers expect you to get fairly personal on your CV. Along with details like age and nationality, they expect to see marital status as well. They even expect you to include a photo when you apply for a job.
Not only that, it seems to be fairly common practice to be asked in an interview if you have children. If so, they'll ask how many. If not, they will ask if you're planning on having children.
Let's be honest: I'm clearly a bit of an open book. I keep a public blog. I'm not actually personally concerned about answering the personal questions, as I don't think my honest answers will hurt my chances at getting a job.
I do find it surprising, though. As well as an extraordinarily unsubtle discriminatory tactic.
I wonder if they think we don't know...
