I interviewed for Palantir in 2010 for a QA position. They flew me in from East Coast, and took good care of me. I didn't accepted the offer as I went on to accept a SW position in a different company. I didn't felt like I was biased against.
I'm not sure about Palantir's bias against Asians, but the tone of comments here are surely negative and partially racist. Let me think, if I really meant "racist". May be it is the fear of competition, usually shown by below par individuals, or may be just signs of arrogance.
Either ways, I am N.E.V.E.R. going to apply to companies like Palantir, Theranos, Snap, Reddit, Path, etc. Damage is done. Congrats.
p.s. Throwaway account.
