WHAT LANGUAGE SKILLS ARE NEEDED?

When applying for a job for which English is required, you should find out exactly what language skills are needed and at what level. Do you have to be “fluent in English” or do you just need “a good knowledge of English”? Are writing skills more important than speaking competence, or vice versa? Also, does your employer want proof of your language skills in the form of a qualification or certificate, or is previous experience working in English more important?
