I interned there one summer about 10 yrs ago and i already noticed back then that some departments were composed either entirely of indians or chinese employees.

The Cisco case was dismissed as false recently. The person was found not guilty of any caste based discrimination. Caste issue in America is mostly made up. Indians who have money to go from India to US don't care about castes in the first place

Cisco did not have any problems, it was Equality Labs which brainwashed an employee to file a lawsuite against his manager (who happened to be Christian). Not only the lawsuite has been dropped the last time I checked the victim (the manager accused of discrimination) is countersueing.

Equality Labs is behind these sort of plans and propaganda.
