Hi,
It is good that you have made a decision on the MBA specialization and your past experience is definitely going to help you in you the course. Best college in India accepting GMAT is ISB (Indian School of Business) Hyderabad, but you have to check the eligibility criteria in their website or drop a mail to them for your query. Symbiosis University also offers a MBA in Healthcare. NITEE or SIOM for Operations or Industrial Management.
I would suggest that you to appear for CAT, as well if you want to increase your options in India as all IIMs definitely are a very good for the management courses. I am also a Mechanical engineer pursuing MBA in Marketing after 2 years of experience. And, trust me the working experience really helps in a better understanding of the subjects. Regards.
