When I worked in IT, the standard technique Western employers used to practise discrimination was to use independent recruiters to place job adverts and vet candidates before they were forwarded to the employer. When the recruiter and employer had an informal conversation a little later, perhaps over lunch, the employer would casually let slip that "if the new employee could speak another language, she would be able to interact easier with prospective clients", which the recruiter took mental note of before changing the subject. But perhaps things are different nowadays.
