B.Tech Scope

Hi,
Yes, it is a good option to do MBA after B.Tech. It enhances your skills in management and the already acquired technical background. Doing management course inline with your technical will be a 'cherry on cake'. Many engineering students go for finance, marketing, operations, HR and mass communication. These are the most suited ones to engineers. They always find it easy to tackle these courses. Streams like finance is much related to day today account transactions which are easy to realise and understand. As it also has flavor of mathematics in corporate finance or determining risk and variance in investments, hence it is liked by most of the students. Marketing requires much of analytical and reasoning skills. Engineering graduates find HR very much related to what they have already experienced, as it includes employee management, resource management and customer relation courses. To sum up, it is a positive point in your CV to have MBA degree from a reputed institute.

Hello,
There are wide opportunities available for these graduates in both private and public sector. The value of B.Tech is obviously more than B.Sc. If we talk about career then the most valuable area in this field is Research. You can work as a research scientist in institutes. For this, you can prepare for CSIR net exam, which is a national level eligibility test for science students who want to pursue their career further as research fellow or assistant professor.

But, if you are not interested in research work, then you can also work as a software developer or a web developer in any software company, work as marketing manager, quality control officer or production in-charge, work in healthcare, food processing, agriculture, pharmaceuticals fields. You can prepare for civil services and other government exams as well like SSC, UPSC, IAS, etc.
I hope it will help you.
Best of luck!
