Had several interviews, all on phone. I was interviewing for this role with Facebook's new Internationalization (i18n) team. I sat in for two phone interviews, both conducted by the same person and got a regret email after the two interviews. It was hard to make out the interviewer's accent, but I did my best to answer all questions that he asked. It sounded like a great position to work in, I am sure whoever got/gets it will thoroughly enjoy the work.
