I guess that's because we get more Indian referrals from a team with more Indians. At least my current team is dominantly Indian because of this reason.

Also, I personally feel there is fundamental difference is how Indians interview the candidates. Indian interviewers usually try to identify the weakness of a candidate (if there is a fullstack opening and the candidate's strength is more on the backend, the interviewer leans more towards frontend to identify the weaknesses of a candidate). Non-Indian interviewers most try to find the strengths of a candidate. When I attend interviews and see a panel with Indian names, I know that those slots suck.

Of course exceptions apply for everything..just my observation being Indian working in Indian teams..

True, and it's true for other nationalities (Asian specifically) too. It's a shame that we talk about merit and behind the scenes it's all a sham with with cutbacks and shady hiring practices (and I'm saying this as an Indian citizen in the US).

This is pretty much true of any group, it would be absurd to deny it.

I'll probably get in trouble but russians don't like to hire russians.

Discriminating against Russians is OK. No worries :-)

Technically this is true, sadly. Nationalities are not a protected group.

No its not. Labor laws in the US specifically state you are not allowed to discriminate on the basis of national origin.

Has also to do with the H1B employee lock in benefits.
