Swiss here. Many if not most not actually speak two languages (we have 4 btw) or at least not enough to have actual conversations. I even know people who live in split cities (also that's a thing, one river side German and one french) who basically avoid the French side and barely speak it either.
There are many exceptions to this for sure, after all German part has french for like 4 years at school. And older people more likely actually learned the language to the point of speaking it, younger people are usually much more skilled in English as their second language whatever they are French, German.
