Congratulations!!! Even though most people know what MBA IS, a lot of people don't exactly know what it DOES. It's kinda like a supercharger for your career. Take whatever degree your undergraduate studies are in and add to that a strong knowledge of how businesses operate, and you are preparing yourself for a career in management of your chosen field or for branching out into an entrepreneurial venture.
Before MBA I was an engineer. Nothing wrong with that.
After MBA I progressed to a supervisor of engineers, a manager of a group of departments, and eventually a director of product planning.
What area are you focusing your career towards?
