While the advantages of proficiency in a global language like English or Mandarin might be obvious, studies suggest that having any second language can be impressive to an employer.
An additional language can be useful in many contexts from an employer's perspective, and it does say something about an individual. In particular, it suggests you have the ability and flexibility to adapt to a global environment, giving one an insight on communication that a monolingual person doesn't have.
Students should be given the chance to develop knowledge of more than one language as this is likely to be a benefit in the unknown employment market of the future.
