There are 4 core branches of engineering, i.e. mechanical, chemical, civil and electrical. Each of these branches have developed into specialized sub branches. The number of engineering degrees available has increased dramatically. For example, electrical engineering is further divided in specializations such as electronics, instrumentation, telecommunication, computer science, information technology, etc. Mechanical engineering also has specializations such production, aeronautical, etc.
The scope for B.Tech CSE and ECE graduates is highest. Mechanical engineering is evergreen branch of engineering with not much change in scope in last 5 decades. You must chose branch of engineering based on your interests to excel.
