It's normal - at least for the big US companies, even with a large presence the culture is highly American. I remember when a VP of APAC sent a org email expressing strong feelings about the Black Lives Matter protests, and it was quite awkward since that wasn't really an issue discussed outside the US - he couldn't even understand how it couldn't be an issue for everyone.
Getting to hit the culture filter very early in interviews is probably a better outcome than ending up at the company and feeling awkward, not sure how intentional that is though.
