since airlines aren't opening any doors at the moment I'd like to discuss prospects of working as a flight instructor in India.
i don't have a CFI but could some suggest a good school (in india) to train and does any school support the candidate after the completion of the course?
any information will be appreciated.

looking for the same anywhere in the world

A quick Google search reveals the following names that offer AFI flying -

1. Chimes - Dhana
2. Saraswati Aviation - Sultanpur
3. Flytech Aviation - Hyderabad

Also check the list of schools currently approved by the DGCA for training.

There may be others.
