I apply online for HS teacher then they text me for the interview. I undergo 2 interviews but before that I took an aptitude test. My 1st interview was with the owner of the school afterwards I was endorsed to the head teacher, which was my 2nd interviewer. After that I have my Demo Teaching, she gave the topic and 2 hours to prepare the lesson in PPT. So, the Demo is on the day of the interview, so be ready.
