Paper doesn't seem to mention what the motivations are for doing this other than a vague reference to 'keeping a talent pipeline'. Its far more likely that they are being financially incentivized to do so, perhaps to meet H1B requirements.
I interviewed at a popular us based k8s ops/networking company that ended up being 90% Indian staffed. The non technical recruiter basically neged me the entire interview, was very clear after the fact he had no interest in hiring me.
