This is basically invisible to "us" (assuming you're not Indian); I'm a comparatively well read westerner regarding this issue but I have no practical ability to spot the subtle signifiers that let people familiar with system glean who "belongs" to what caste if they care to. Also non-Indian managers are very unlikely to be interested in discriminating against specific subgroups of Indians even if they're huge bigots or something, so this is a pretty specifically inter-Indian issue.
