Indeed, Crossair's preferences are first focused on Swiss Nationals. However, they don't just hire you because you're Swiss. Three friends of mine were not hired because of psychological issues and they were Swiss. They didi not fit into the pricture Crossair wants to have. On the other hand I know of Noth American guys and a lot of EU folks who were hired. The swiss market is obviously not able to produce enough "qualified" pilots for CRX and also SWR. The fact that we all have CPL/IR/frozen ATPL or even better lot of turbine or jet hours doesn't automatically mean, we have the job.
You have to fit the selected company's mask, no doubt about it.
Switzerland is short of qualified people and therefore needs also foreign pilots. A good frien of mine started with Crossair 4 weeks ago. Out of 19 in his class there were just two Swiss pilots including him. You see, your chances in getting a job within Crossair are quite good, if you fit into their picture.
Good luck!
