Like Leffeboy – also Belgian expat
In Brussels there are lots of English language positions but the further you get away from the city the more unlikely you would find something. I speak English, Flemish fluently & enough German to disgrace myself.
I’m based in Brussels but work all over Europe. It seems inconceivable to find skilled work in many countries if you don’t speak a local language. You would need a very specialist skill to overcome that boundary. English levels are very high in NL, DK, SW & NO hence its probably more feasible to work there (in English) if you have some work related skills.
No-one in my team speaks just English even though our corporate language is English.
