I applied for a job with an American software multi-national a few months back. I received an automated email claiming that they were "excited" by my interest in the role. Six weeks passed without any contact whatsoever from them, after which I received an automated rejection email, which began: "Dear [redacted], We've really enjoyed getting to know you!"

Don't get me wrong, I don't think that they had any obligations to me, but to my European sensibilities, the blatant insincerity of those emails borders on the offensive.
