Need suggestion

I have just completed 3 years in TCS . I am working on pretty good technologies in my current project Java + python full stack , Google cloud and Vertex AI . There was an opportunity to join a TCS sponsored Mtech programme in AI at IIT M (https://code.iitm.ac.in) which I took part in , gave entrance exams and now got selected in . The catch for this is , if I join this , I have to stay back 3 years after completion of the course or else pay 15 lakhs bond amount . I am divided on whether to take this opportunity. On one hand. I am confident in my skills that if I switch now I can get 100% hike or more ( digital cadre) . On the other hand , this is a chance at doing Mtech at one of the best colleges in the country with peanut salary at the end of 8 years. Would love to know how you all think about this.
