Caste is another term for race. Both terms are not terms that designate bioligical properties of a person but social grouping based on perceived social differences (e.g.: even if your skin is lighter than some white people, having 1/8th black ancestory will get you classified as black, while actual african americans with wealthy had become "honorary white").
Like others have said, you can't say "I won't hire you because you have red hair" either for example. If I make up the practical equivalent of a race and arbitrarily deny jobs to people because of it, that violates the equal employment opportunity law. If I deny jobs because of skin melanin content, regardless of sociap definitins if race, the fact that I don't call it race does not change the fact that it is "race" , a classification of humans that identifies behavioral,physiolgical and intellectual traits based on membership to a unique genetic ancestory.
Accent and color of your cloth are not bioligical hereditary properties.
Isn't it the other way where profession is based on the caste you are born into? You make it sound like a child born into a lower caste can choose a profession that lets them join a higher caste. It's not different than american back slaves being born into slavery, if you call slavery a profession or jim crow era legal segregation limiting jobs based on race.
