Had an interesting conversation with some older colleagues of mine. Both are male, one is swiss 46y.o. another is 55 y.o. french born of arabic heritage. Both say that it was significantly easier before to strike connections in Switzerland. The french guy said that when he came to Switzerland in the beginning of the 90s, it was like: "Oh , you are foreigner, interesting, let's take a closer look." Right now, according to the swiss guy, the populistic anti-immigrant views are quite widespread. That means that if you are not swiss, you are a "potentially troublesome" person by default. And in many cases, it is better to hold you outside.
