Completed the online application and received an email the next day to schedule a mock interview. After taking a few days without scheduling, I received an email that I could do an "express interview" to send a recording of myself using their teaching methods. After doing that and passing, I had to complete a "mock class" with an actual person. I failed the first mock class but pass the second time. I believe you are able to retake it more than 3 times.

Interview process was relatively fun and easy if you're comfortable doing part of a mock teaching lesson. They may do it differently now, but that's what I had to do when I interviewed.
