^The proficiency is rated from 1 to 4, they're looking for a 2+ level which is half way up the scale.

It's a speaking test over the phone, 30 min to an hour, they won't examine reading/writing, but it's definitely a structured test where you won't be able to BS your way through unless you're semi fluent in the language/culture (depending on the language)

If you can speak it to a point of holding conversations and critical thinking, definitely worth a shot.
