I had a big group of coworkers from EPFL when I was working for Google Switzerland. At some point, I actually questioned whether we have a bias for these schools. EPFL or ETH are definitely not something I'd consider as just "Swiss education system". These schools are what Stanford or Berkeley are in their region, and are highly international.
