sir/madam, i will join nit at the age of 20 for btech, and I will complete at age of 24, will there be any problem in placements due to age?
No, I dont believe there would be any as such issue. Utilise your BTech years, get a good CV, strong Academic Credentials, Internships and Projects, youll definitely bag a good Placement in your Final Year. Ensure not having any backlog in studies in the Four Years of your stay at NIT, at this is something which affects Placement Prospects.
