My point is that I think that an Asian person, applying to a company known to be favorable toward Asians in hiring, would signal their ethnicity somehow in their resume. At least, that would be the smart play for that person.
The "tell" that I'm primarily relying upon is that you often drop articles where a US-native speaker would use them. Just one example: https://news.ycombinator.com/item?id=13197570 (that was as far back as I went) I think most native US speakers would use "the gun industry" and "the film industry". Several later comments drop an "an" or "a" article as well.
You also have a habit of using a comma splice rather than a semi-colon to join sentences, but that one is harder to place geographically, as it's a somewhat common trait within the US as well. In my experience, it is often a trait of European native speakers who learned English as a second language, but is less reliable than dropped articles.
Definite article rules do vary a little bit, though, so extra definite articles would be a good indicator of European native speakers...
I have never witnessed that mistake with non native English speakers.
And you can also make the early stages of your interview email or text-chat based (or just a Google Doc, like some companies do), to eliminate any potential bias in things that can be inferred from voice like accent, region, and gender.
Obviously once they're on-site for an interview, you can't anonymize much anymore, but anonymizing every stage before that seems like a win-win to me (excluding potential costs of implementing the system).
