I'm from Germany and i'll be looking for a job (software developer) in Belgium later this year (Flanders area like Gent, Antwerp, Bruges). My English is fluent but i don't speak a word of Flemish. Many jobs i found require both languages even though the job offer is written in English.
Would it be wise to contact the companies before writing an application to ask if they accept English only speaking applicants or if they offer something like a language course?
