> Do Indian children have their major chosen for them via parents, tests, or administrators?
Parents. Their future job is usually decided for them before they're even born. The number of people who go into a particular profession because they enjoy it is exceedingly small.

This is patently untrue. Parents usually have high expectations of stable, well-earning jobs, but in no way decide before they are even born. It might apply to the minority of businessmen who insist that their children carry on the "family business", but even that is rare.
