Very relaxed and easy to follow interview process. They will first email you instructions to record a lesson teaching some concept like accessing the last character of a string. The second round is a mock session where you do two 15-20 minute live mock lessons to the interviewer. Interviewer is very nice, and the whole interview felt relaxed.

record a demo class to show that you are capable of accurately demonstrating some computer science related concepts. It went fine for me, the interviewer was nice. Overall you just have to be clear on your words.
