Why do they ask for that information anyway? So they know to capture you alive when you got a job that’s in demand in the destination country? Or do they hope to catch terrorists by fishing for ‘bomb builder’?
It really feels like some by-gone form field so many just keep putting on there because it's always been there.
So many places, including doctor practices, ask for this (in Australia), and you're just left feeling, why?? This is useless information that they don't need to know.
For tax, home loans, etc, sure, that's relevant information.
A doctor has a reasonal interest in your occupation. For office workers they’ll know to expect back issues and may nudge you towards preventive measures, for instance.
