You can guess where that ended. In case you can't: "Who did I think I was to refuse their offer to come to America to partake in this great opportunity?".
Interesting attitude change, turning on a dime they went from all smooth and friendly to outright hostile, and that on a track that they initiated. Very weird.
The follow up is usually "Why do you want to leave your current company?" replying with "I'm not, your recruiter said this was a cool place".
"Why do you want to sell me this apple?"
"Be... cause... I grow apples? To sell? And you said you want one, and are holding money?"
This was at the end of the process, after I'd already interviewed with all the technical folks and all the managers and they all wanted to hire me.
Apparently the desired answer was "no." My actual answer was something like "WTF are you talking about," and I somehow managed to get hired anyway. I later heard that if I'd answered "yes" it would have been difficult to overrule HR and get me hired. LOL
