One has to download their mobile app and fill in the application form. You also need to need to upload your passport, qualifications and do a voice recording. Someone interrupted me during this process, and when I returned to the app, they sent me a message they rejected my application. No reason supplied. How could they reject an application that is 50% complete? What are they doing with my private documents like my passport? These days we have to be more aware of identity theft. Right now I feel I made a huge mistake to apply and trust them with my documents.

Pre-recorded, mock class. You are basically teaching a class to an imaginary student. I heard back within two days, in which they hired me. I would definitely recommend practicing before you record the interview class, and make sure you are prepared with necessary props.
