Have you found there to be a significant language barrier when moving to Switzerland? I know Europeans generally know English, but is there an expectation that you speak German or another local language?
That said, in our case, working for Banks, you do still connect to the 'old school' Swiss buissness who are a little less English driven then the Tech sector. That has caused some issues for us, but not all that significant.
The police l, if you have to interact with them, might treat you more roughly if you don’t speak the local language.
Outside of major, cosmopolitan cities (pretty much Zürich and Geneva), I'd say there is an expectation to speak the local language. Anything official I've done has been in German.
