Just recalled my school work experience.
Career advisor: "What's your dream placement? Think big!"
Me: "I'd like to work in TV, film or..."
Career advisor: "What's your dad's job?"
Me: "Sales rep in a menswear firm"
Career advisor: "Ok, so I'm placing you in a dept store in menswear. Have fun!"

@Richard_Littler We didn't get work experience. I think we were expected to magically know about all professions without being exposed to them in any way, same as with sex.

I'd have loved to be able to reply "CPO on a nuclear submarine"
