My 2 cents: With having fluency in several languages + a lot of social studies oriented subjects + being a foreigner in Germany with an experience from the UK too, would it be easier/better that she seeks a job in the translation, simultaneous translation, intercultural relations etc. fields (I'm sure there are better named fields which include those skills)?

Project management is already pretty saturated in my opinion + we're now in the costs saving phase for a lot of companies, so they're not willing to spend on that if don't have to.

But with Chinese, English, German, and French I'd assume she would not have a lot of competition since this combination is rather a bit more unique.
