Hey there
Metallurgy is an evergreen branch and the seats for metallurgy is less compared to other branches like mechanical, electrical etc. Also nit Trichy is the top nit and so if you are getting metallurgy there grab it. If you are interested in core sectors then you will get a good placement from there in core companies also as everyone knows that Sundar Pichai was also from metallurgy and he got a job in Google so even though you want companies like Google Microsoft etc still this will be good chance for you.
Good luck
