The word "NATIVE" is discrimiNATIVE my friends... Doesn't matter if you r fluent in English, or if your license shows level 6. They want you to be born in an English environment whatever your english level. That's unacceptable.
Be fluent in German, Spanish or even French and you will have a chance to get a job with one of the majors.
Once again this post is not a confrontation between natives and non natives and I would be horrified to see German Native, French Native, Italian Native adverts...
