Hello dear aspirant

In the current scenario,  computer science engineering is one the best course to give you a job,  it can give you a direct campus placement after 4 years of you B.Tech course whereas B.Sc Chemistry isn't a job oriented course,  it's good if you are planning for long term and appear for some government jobs like one in UPSC.

Hope I am clear

Hello Mayank, It depends on what kind of work you want to do. If you want to want to become a civil services officer, then civil engineering is best for you. If you are looking for technical jobs then undoubtedly Computer engineering is best for the job. CSE engineers are required in most of the companies, so they have very high demand. BSc chemistry too has job opportunities but they are limited.
