After doing two successfull interviews they called me back in again and as that was going well they tried to trip me up. On my CV I inidicate that I have two European languages so they promptly told me I would now be interviewed by 2 people in each language. In fairness, it did say on the job description that European languages were a bonus. Imagine their faces when I actually pulled it off.
Admitedly my German was rusty since I havent used it much since I learnt it at O level. It didn't seem to matter and the guy that I was talking to commented that all was well (in German). Swedish on the other hand was a blast. Having lived there for 4 years fairly recently I chattered away, managed a few funny storied and ended up asking the Swedish guy all about his home town and what he missed most!!
They sadly had the last laugh since I didnt get the gig!!
