Dear Aspirant,
There is a famous saying "CHOOSE BRANCH OVER THE COLLEGE" and as you are already interested in computer science, go for it. Metallurgy is not a very good branch while CSE is the top branch of engineering. Almost every college has a decent placement for their CSE students.
Moreover, it is on the most popular and fast growing branch. Students from various other branches are going for jobs under CS/IT sector. If you did your engineering in this field then you'll have an upper hand on such students.
Hope this helps.
Thank You.
