Funny. I'm pretty sure I failed a technical interview many years ago due to the whiteboard exercise in which I used LOOP pseudocode to solve the problem. They weren't Lispers and assumed the code wouldn't work, but I was sure it did (I couldn't explain why though, at the time, as they made me doubt my solution).

Either way I think they were looking for a recursive solution. Oh well, they still invited me to lunch, though.
