Since I have been researching about the Indian engineering education system for last 10 years hence I have an accurate answer to this question.
Since Indian engineering curriculum is 40 years old hence no Indian engineering college produces any skilled-employable Aerospace Engineering professional and this is the reason that there are no core private Aerospace engineering companies in India. This is also the reason that none of the internationally known Aerospace Engineering companies carryout campus placement at Indian engineering colleges.
Indian engineering curriculum is so much meaningless and worthless that ISRO allows all the mechanical engineering degree holders to apply for Aerospace BTech/MTech job openings, thereby showing us the standard of Aerospace Engineering education in India
