I applied online. The process took 2 weeks. I interviewed at Futura Language Professionals (Madison, WI) in Sept 2018
Interview
Very positive overall experience. Involved discussion on why you love Spanish, how much you have worked with kids, and has a portion where you speak in Spanish. You are also expected to prepare an activity for a class based on instructions they send you and present it to the interviewer.
