(In fairness, they never got the chance - I did break the ice by observing that after walking past that office door down the hall, I realised why Swahili had been on the list of qualifications - so were they interested in looking at the work samples I'd brought along, or should I rather fail the Swahili test first?)
Oh, if I were them I'd just say something along the lines of 'We've been working with an East African university (I believe their preferred candidate had spent some time in Dar es Salaam), and have found a working knowledge of Swahili to improve cooperation greatly' or something to that effect.
