Dear Vivek,

First of all, determine your area of interest as textile, biotech and mechanical are different fields not related to each other. And all three of them have wide scope in future as well. Going with textile you can get job in quality control, sales technical, R&D, production control, process engineering, corporate management, planning and maintenance of textile machineries etc. While, biotechnology has expanded to diverse sciences like immunology, virology and other subjects like health, agriculture, cell biology, plant physiology, seed technology, etc. The job of a biotechnologist is to modify or manipulate living organisms in laboratories to develop new products. Moreover, mechanical engineers have many opportunities in aerospace, automobile, chemical manufacturing plants, oil exploration, railway coach factory, research, and development etc.

So, please choose accordingly as per your interest. Coming to institutes, IITs(Indian Institute of Technology) have quite great scope. Whether it is Delhi or BHU, you will come across great placements too. Also, choosing dual degree program will save your one year.

Hope this helped in resolving your query.

Good Luck :)
