Educational Planner at San Jacinto College
Knowing more than language helps you stand out - something to talk about during interviews. It's difficult mastering one language so if you're able to do that with more than one it can show that you have serious skills!
But I would also say that it really depends on the career. If you're planning on conducting international business, teach overseas, work abroad or work for a government agency, or become a translator then yes, additional language will definitely be useful.
