Explain to them that I'm unfamiliar with the language Do my best to make heads or tails of the situation If I feel i've done well, play up my ability to learn new things quickly. If I feel i haven't done well? Smile, shake hands, and make sure I'm the one who tells him "You know, I just don't think this will be a good fit for me. You need someone with more expertise in this language", and go and find myself another interview.
