Hey guys a buddy of mine consulted with his Japanese girlfriend. She feels that he should treat the JET interview like a Japanese interview. For example saying, "失礼します” before entering the room and sitting down.
While he is at a pretty high level (close to 2級), I wanted to caution against this. I feel that they are hiring a foreigner to speak English, to teach their culture to Japanese students and to be different from Japanese people. I feel that of course Japanese language ability is a plus but going in with your J-go guns blazing might look like you're going to Japan for your own language development, not to help J-kids with theirs.
I think its a fine line to walk.
Of course if they bring up Japanese, I wouldn't recommend shying away from it. Let them bring the Japanese to you. I feel like they are expecting you to come in using English and it might throw them off. I think finishing in Japanese seems ok to me, with a bow and a "ありがとうございます。。。。。。。。”
What do you guys think?
