I thought I'd fucked up a good few preliminary interviews because the interviewer sort of got bored a few minutes in and went "yeah, that'll do".
And then a bit later I'd be told I'd made it to the next round.

A mate of mine who works in sales had the following interview once:
"Do you like beer?"
"Yeah"
"Do you like birds?"
"Yeah"
"Welcome aboard"
