How important is knowing a second language when working overseas?
I'm really interested in working overseas in the future, particularly in Asia or Europe. Does anyone know how heavily knowing a language is judged when you apply? Ive looked at threads on here and some people say it doesn't matter and others say it's an absolute necessity to speak that countries language to a native fluency level... so either it depends on the firm or people on here really have no clue what they're talking about. So, can you only give advice if ACTUALLY know about international requirements.
In specific, I'm interested in Singapore, Switzerland, Russia and Hong Kong. I'd also be happy to work in one of the lesser known Asian countries like Thailand etc, (if they even have a banking scene there). I've been learning Russian and mandarin this past year and I don't plan on moving overseas until I work for a few years in the USA. So, in 4-5 years I'd assume my mandarin or Russian would be somewhere near "fluent" although probably would never reach "native" level.
so yeah, I'm asking this because I wanted to know if I have a shot without being a native speaker. If so, I will work hard at mandarin or Russian (depending where I want to apply to) and give it my best shot. However, if native fluency is 100% required then I guess I'll just work in the USA and move overseas when I retire.
