The interview process was making a fairly long and thorough video, answering several questions, so you did not actually speak to anyone live. (You've got a glitch here: Your software tells me I can submit this description as-is, but then I get an error telling me I HAVE to add more words and I can't proceed without doing so, so here are my extra words.)

You are sent a link to an online video interview. They ask you about previous tutoring experience and the last question was asking you to do a mock-tutoring session. It's very awkward because you have to make up what you want to teach on the spot, but you get unlimited time to think of responses.
