Possibly illegal, but the mention of being younger makes me think this is less for a "real" tech job and more for a "normal" job or a code monkey position where you really just need semi-competent people who can fill seats and do a modicum of work.

When I was younger I applied for a lot of jobs like that (supermarket, bookstore, data entry) and dealt with automated quizzes like that. None were quite that blatant, but even in my late teens I understood a lot of the questions were about risk assessment.

So it stands to reason that a huge concern with this was keeping insurance premiums down.
