Too many diversions ahead ! I would suggest to choose whatever you like the most. You must already be aware about your engineering degree. Going for job and doing MBA both are good. Even if you go for job most people comeback to complete MBA for proper growth. So suggestion would be go for MBA now ! if its financially feasible for you family. Look for good colleges IIM, IIT, NITs, Symbiosis, Lovely Professional University etc. Placement should be most important thing to look when going for MBA.
