at IIT HYDERABAD will tech companies hire students from material science and metullergy department?
It depends on the companies policy only if they are willing to hire students from metallurgy department then obviously you can sit in their placements but if they don't then you can not do anything though many tech companies do allow students from all branches but many do not as well so if you are going to join metallurgy then think and join accordingly although you will get a great coding culture in iit hyderabad also you may go for off campus placements as well.
