This isn't quite accurate either. You can stay as a tourist, but otherwise it's a good old Catch 22: - no one will allow you to rent an apartment (and therefore get a permanent address / residency) without a job contract and without a residence permit - you won't get a residence permit without a job contract. - but if you don't have a permanent address and a residence permit, you could just as well apply for jobs from your own country, because what's the difference?

I guess it is easier to go to job interviews if you are staying at an AirBnb, but otherwise no point in staying in Switzerland, unless you are a millionaire, in which case you can support yourself anyways, so the above does not apply to you.

This is actually one noteable difference to EU countries, where you can just move to as you want, you most probably need to register but don't need to apply for a work permit separately.

PS. There is another way. Many people live in Germany, close to the Swiss border, and commute to Switzerland. But if you are a German you already knew that, and if you are not, it's probably not much easier for you to get a job this way :)
