Just needed a letter of recommendation and proof of experience. Also needed to write letter of interest. It's best to have a French professor write the letter. If not you have to take a test to determine how fluent you speak the language. Shouldn't be a problem if you've spoken French for several years. The test is just to determine if you would be able to communicate in France without a problem.

More written documents and recommendation letters. no actual interview. Applied in Dec. Was put on waitlist and then accepted in summer. Process is long but its a great experience. Definitely recommend
