1) Is the pronoun "what" correct in questions about professions?
I was taught that "What is he?" means "What is his job?", but personally I have never heard this question asked by those who speak English. So when asking about somebody's profession should I say "What is his job?" or " What does he do?"
2) How can I ask about a future profession: "What will you be when you grow up?" Sounds a bit weird to me, I would say "What job will you choose... ?". The same with "What are you?" Being used out of any context it seems odd... Thanks.
