I have done BE. I have more than 10 years of experience in the IT field. Should I opt for MBA now? Is it a good choice?

You can try for ISB or any foreign university. For that you have to give GMAT. If you want to gain some knowledge and improve your career prospects then go for it. But keep in mind you may not be able to get into IMS as maximum experience of 8 years is required for their executive programme. Beyond
