Japanese for Japanese candidates; for candidates from overseas, whichever language they speak most easily. The interview language is set per job — Japanese, English, or both, in which case the candidate chooses at the start. Either way the recruiter reads a Japanese report, and the quoted evidence carries both the original words and the Japanese.
