Which specialisation should I opt for in MBA?

Hello! Being from a B Tech background, I think pursuing MBA in Operations or IT is the most ideal option for you. Still you may pursue any stream among HR, Finance, Marketing, IB, etc as per your interests and career aspirations. https://www.shiksha.com/mba/articles/top-5-mba-specializations-in-ind

B.Tech and PGDM is a very strong combination as it fetches fat salary, specialization suites for this combination is marketing, international business management, finance, entrepreneurship and even digital marketing is good enough. For more, you can log on to www.taxila.in Good luck.

If you like practical things than you should go for finance but if you like theories than other options like marketing, HR, etc.
