I don't know about other area's, but as a developer it is well doable to get a job in Switzerland. What you're saying about the Swiss hating foreigners is definitely not true, I would even say the opposite. But the competition for IT jobs is a bit more tough than in some other countries in the EU. I don't know why that is, maybe it's because of the outflow of the ETH or maybe it's just that Swiss jobs are so popular with foreigners.
