You are a techie who want to do an MBA?
What motivates you to do an MBA my friend?
Samy, I am not an MBA myself but I have worked in various management roles, hired various MBAs and am an entrepreneur. I can tell you few things from my experience. If you manage to switch your job role also to a management role (assuming that's why you want to do an MBA) then yes, MBA will help you accelerate your career. It depends on you. I know big companies might not let you do that but you have good chances of trying that in startup (getting into marketing, IT consultant, BD, operations role)
Firstly answer yourself where do you see yourself 5 years down the line?
Talk to people who are in that role now and see if you would do an MBA will it help?
If you want to completely switch your field then MBA is a very good option but then classroom MBA is preferred. What is stopping you from a classroom MBA my friend?
I think SIBM is a good college in itself. You have to talk more to the seniors of the college to find out how much internships, projects, placements etc are done for the distance education student. They will be the best people to tell you the reality.
Hope it helps.
