Reddit reviews Living and Working in Switzerland: A Survival Handbook

Wherever you move, invest 100% in learning the language. If you are moving into the Swiss-German speaking area, this will be much harder than the French or Italian area, but you must do it.

A customer of mine is originally from India, and he only conversed with his wife in English when they lived outside of Switzerland. When they moved to Switzerland, upon landing she said, "these are the last words in English I will speak to you, from now in it's Swiss-German." He thought she was joking, but she wasn't. It was tough love, and 6 months of hell, but now he speaks Swiss-German like a local, with no accent. This is extremely rare. And even as someone who is clearly not Swiss, he is 100% accepted into his village and really enjoys life here.

I also recommend this book:

It has tips and tricks that even most Swiss don't know.
