Hi
I'm from India too and I'll also be applying to Yale MBA in fall 2022. I am enrolled in a 3 year graduation program currently.
Have you heard of the 'Silver Scholar Program' at Yale? That's a program especially for recent graduates. You can apply to it without work experience. Search for Yale Silver Scholars Program on the internet and you'll find its website.
Ping me if you require any other help. There are many deferred programs in different schools which provide MBA for recent undergraduates. Do checkout the list of top deferred MBA programs around the world.
Cheers!
