In my point of view pursuing MBA after engineering degree is one's personal interest. It doesn't mean a man can grow after MBA. Technology is growing fast day by day. Done MBA after the Engineering Degree is added advantage. But in India so many political leaders are running our country without pursuing MBA. So managing skills and leadership quality depends on ones own skills and interest.
Engineering course develops Analytical and logical skills in an individual and when these skills are combined with managerial skill-It becomes an Unbeatable combination.
Statistics also prove this fact as most of the students who cracks CAT and other exams are engineers.
For any foundation your base should be strong, and engineering provides us with this as in engineering we learn technology and in MBA we learn how to implement these technology in various aspects of organization.
Also today is the world of globalization that involves not only transfer of technology, products and goods but also services that involves human interaction, so MBA that teach us all this with Engineering becomes a best suited Combination.
