which engineering is good aeronautical, automobile or mechanical, if i like to work in Kerala state ?
as per your college requirement, choose the best option you have . don't opt for any lower option. when you sit for placements, you can request your company for a Kerala posting or somewhere near.
If you are interested in doing something out of the box, I would recommend you aeronautical or aerospace engineering. In future years could join ISRO by that way.
Mechanical engineering is a broad stream as it is combination of various branches like production, automobile, etc. So, in between automobile and mechanical engg, I would strongly recommend you mechanical engg, as it broadens your future career opportunities. You can do specialization in many fields post your degree, like robotics, marine, aerospace, aeronautical, automobile if and only if you graduate with mechanical engg background.
Best Luck!
It's really good for your idea but if you're native of Kerala I want you to choose different verticals of the world to go and work there because you need to know what the outer world is. If you really want to work in Kerala, then go for automobile/mechanical. You'll be having good future there.
All the best, but take wise decision.
