Many years ago, I interviewed with Jane Street. They asked me C++ questions and if I am willing to learn OCaml. Sure, I can learn any language. The position was given to someone else who already knew OCaml. They use OCaml for everything, building software to distributing it etc. That's my interview experience with them. I think they chose that language because it can be as speedy as C++ with proper knowledge and optimizations. I do not know OCaml besides learning it when I worked with researchers/mathematicians who wrote OCaml and i had to understand the code.
