I never see ethnicity after the first 5 seconds. If you can talk shop, you're cool, period (in my subjective brain). This is why I have issues with diversity discussions; it's like forcing me to acknowledge the elephant in the room that doesn't actually exist in mine. The best programmer I know is female (and I have told her as much), the second-best is half-black, the third-best is a white Jewish Stanford grad, and somewhere way down the list is curious old me. Who is still giving a shit about this stuff? (Disclaimer: I'm likely as white as can be, the Aryan ideal, dirty-blonde blue-eyed German firstborn American).
But for what it's worth, my latin-american brother-in-law introduced me to ceviche (he makes it himself), and that shit is the bomb-diggity
