What is today’s hottest job skill?

It’s not a programming language, it’s not SEO, and it doesn’t run on your Mac or your PC. It’s one of the most overlooked skills on resumes in the US, and will soon be the deciding factor in whether or not you get that top position.

It’s fluency a second (or fourth) language.

“Translators and interpreters are expected to be one of the 15 fastest growing occupations in the nation,” writes CNN money, quoting the US Department of Labor.

The Department of Labor expects 25,000 jobs to open up for interpreters and translators before 2020, which typically require both language skills and a knowledge of a specific field. Interpreters and translators will specialize in engineering, nonprofit, education or other fields.

Language skills are one field in which American workers are seriously lacking, and companies like Amazon, Apple and active others are looking for those with language skills to help them expand to non-English-speaking markets.

And with Spanish as the US’s second and fastest-growing language, the demand is even greater.
