What is the future scopes and companies I can get after completing btech in aerospace in iiest shivpur?what is the highest package I can get
In India, you have institutes mostly offering Aeronautical Engineering.
Now coming to the scope for aeronautical engineering in the country, I won't bluff but it's pretty meagre. It's tough to secure a job post your bachelor's. Of course, there are a few government companies such as DRDO, HAL, and NAL; but most of them require recommendations to get in or may have their own entrance exams especially in the case of IIST to later on join ISRO.
When I graduated from my undergraduation studies in 2015, none of us got a job in a core aerospace firm. And our college, although not an IIT or NIT, was an acclaimed institution for aeronautical engineering. Most of us had to go for Infosys or Google to find some employment.
