I can't take all the credit for learning a language like that. I hear @Le0 speaks Na'viA lot of the staff are actually bi-lingual. We have people who can speak Russian, Korean, Spanish, Vietnamese, Dutch, Norwegian, and others. @MCJackson is also proficient in Klingon.
Besides that, it is difficult to have multiple languages. All of application and interview processes are English, as well as the servers, website, etc.
