Dear Vikas,
First of all they will call the child separately in room for around 15 minutes and give him/her some activities like building blocks, string the beeds and some preliminary introduction with the child like what's our name and recite a poem.
Then once the child came out they will call parents along with the child and ask some basic questions like brief about yourself and your child, why chosen this school and why not other schools like DPS and Apeejay, what will you do if child throws tantrums at home or in public place, what are your reactions about schools having AC facilities as every schools are international.
The same We were asked in Apeejay Noida but the child is seated next to us but with different teacher and asked for fruit recognition and poem and some colors of fruits.
Pl be prepare with such questions answers and all the best.
