Most of the program directors and other technical staff comes from lower ranked colleges like CET Trivandrum rather than from IISc and IIST. They are not based on IIT Jee rankings.

China banned the private tuition for Gaokao. Even before, it was not open to gamification like rote learning a few physics, chemistry, mathematics questions are(in the case of JEE). There are rounds to the exam which deals with latent intelligence rather than rote learning of problems for patterns. JEE has multiple choice questions and other pattern matching questions while Gaokao emphasise on subjective understanding.

Chinese professors are well paid and there are various perks to being a professor in China. Its a lucrative job and was one of the most well sought job before the private sector gained over it. IIRC the cafetaria for professors were said to be one of the biggest perks over working in private sector(jokingly mentioned by a chinese friend). I am not sure how true that is now.
