Hello,

Firstly, B.Tech or BE is the same field that is of engineering. B.Tech is bachelor's in technology where you can choose any branch of your choice like computer science and engineering, information technology, civil engineering, mechanical engineering, electronics and communication engineering, electrical engineering, automobile engineering, aeronautical engineering. There are also many specialisations in CSE like artificial intelligence, internet of things, ethical hacking, cloud computing, machine learning and so on. BE is just known as bachelors in engineering. So it's the same thing.

Hope this helps.
