what about computer science?

Assuming you have asked for scope of CSE so below points are considerable -

Computer science placements are excellent as big names like TCS, CTS, Wipro and Infosys hire students in large numbers not just from computer science department but also from other departments such as chemical, civil, mechanical and electrical. Apart from these service providers, large multinational companies such as Google, Microsoft, Facebook and Amazon hire students from reputed institutions such as IITs, BITs, NITs, CEG-Guindy etc. Apart from these service providers and multinational companies, there are tons of smaller IT companies in India. Apart from software, internet and IT industry, there are other sectors such as data analytics, banking, oil and gas, manufacturing etc. that hires a lot of CS students for their IT needs. Also, Indian startup scene is growing rapidly and these companies are in dire need for smart and bright software freshers and professionals. Many computer science students who are interested in quantitative research, banking and finance join such firms.

Hope this helps!!!
