Fortunately, winds are changing directions. Young Indians have come around to the prospect that engineering, medicine, law or civil services are not the only career options. Success of companies like Flipkart, Paytm have played a massive role in turning students towards entrepreneurship. People in major cities are open to pursuing unconventional careers on Youtube, Instagram, Blogs etc.
But there's still a massive way to go. I'd estimate it will take another generation or two to bring about this cultural change that marks are not everything.
If you need to grasp the intensity of the problem, be aware that multiple prime ministers have made multiple remarks over the years, telling the kids that the exams are not the end of their life[1]. Movies have been made to emphasize that skills/passion is way more important and valuable[2]. To see the after effects of such an education system, read The Made-In-India Manager[3]. Some positive effects are that you get really ambitious and competitive people out of such a system. On the negative side, you'd see that many Indian workers do not really have a hobby or life beyond work.
