I applied online. I interviewed at GD Goenka Public School (Gurgaon, Haryana) in Mar 2018
Interview
Interview happens in 3-4 rounds in which first you need to write down your views about a topic and the personal interview round where in you need to give self Introduction followed by a written test and than the demo . If they liked your demo they will give you a call for the next personal interview round with the management.
It was a long process but if you have good communication skills you can easily get the job.
