It was an online interview, in which I was given 5 minutes to prepare for each question. The quesitons mainly asked about why I was interested in teaching in Argentina, and I focused mainly on my cover letter, expanding a little. I found it difficult to fit everything into the 1 minute window, but with a little practice it wwas ok (I think there were 2 or 3 attmepts possible). All in all, the interview process was quick and easy.
