This book by Angela Weinberger includes excellent tricks and information about a proper job search in Switzerland.
As there are many expat families around 2,5 m and headquarters of international companies in Switzerland, it is very important to follow the right job search method. It is not sufficient to have a perfect CV to be successful in the process. Interview questions and process may also vary despite interviewing with a multinational.
I strongly recommend Angela`s support before you start, during your search and especially right after you think you are not going to make it.
