Someone I interviewed some years back did their interview in F#. I didn't know F# and tried to make that abundantly clear to them, but they persisted nonetheless. I had messed around with O'Caml back in college and so at least had a passing familiarity with functional language concepts, but I really had no idea if what the candidate produced could be considered quality production code. That didn't help their chances of getting the job.
