They must have made a mistake.
I’ve gotten rejected, twice, by companies I positively never applied to. Nor were they any subsidiaries or whatever of other companies.
Then again, one time I’ve also gotten a rejection mere hours after applying.
Also notable: This one time last year when I e-mailed my application and received a very official rejection letter a few weeks later… by snail mail. Signed by the CEO himself. Not sure if that’s supposed to be a badge of honor or something.

I don’t see you guys rating
The kind of mate I’m contemplating
I’d let you watch, I would invite you
But the queens we use would not excite you
