Let's say that an Indian manager hires more Indians because he feels like they are easier to work with. Now, he doesn't just hire Indians, but he is statistically more likely to do so over a large quantity of hires. Is that against the law?
IANAL, but place of origin is one of the protected categories, you can't even ask the candidate in an interview. So I would expect much less discriminate on purpose.
Also, "feeling like" someone's easier to work with sounds more like unconscious bias than reality. And if a company the size of Oracle would make hire/no-hire decisions based on such impressions, it'd be a sign that they have organizational problems.
In New Zealand, we also have this thing called "Kiwi Experience". I think it's just an excuse to pay someone who is new to the country because they have no "Kiwi Experience".
Mind you, some or maybe even most immigrants (at least from my country) have at least 3+ years experience. Job experience means more points for Immigiration NZ.
