Actually the main language in Gent is Dutch (aka the Flemish Belgian language).
At the company offices however we do have 5-10 people who do not speak Dutch. That is why most office documents, emails, internal forums and meetings are in English.
Where a Dutch spoken language is not required, you do have to understand and speak English.
