My experience (having interviewed at Google NYC twice, turned down both times) was that if I asked what language I should, they would always reply with either C, C++ or "C-like."
Only once was a particular language required (I was asked to implement memcpy, in part because the interviewer wanted to test my knowledge of low-level C and void pointers).
That said, I did write one of my solutions in OCaml even though the interviewer did not know the language (I asked him if I could, and he got the gist of my solution).
