See, a plain MBA, or which we call general management gives you an insight into all the basics of management, ranging from Economics to Finance and from Organizational Behaviour to Consulting, while an MBA in international mainly deals with the study of bilateral ties and overseas economics.

An MBA in Investment Banking is majorly finance oriented and will open the doors of many big bulge bracket banks like Goldman Sachs, Barclays, Citi etc.

Hope I have answered your question. All the best!
