What should I choose among MBA in finance management and MBA in business economics? I am a mechanical engineer.

As per my consideration, you can do MBA in finance management. Because this field concern with finances and how to manage it and plus you are a mechanical engineer so you have good knowledge of numerical and maths. It is daily life applicable course which will also help you in your daily curriculum

Master of business administration is a very good course for you to pursue. The scope of job opportunities and salary package for MBA plus engineering graduate is very vast. The course which one can take after B.Tech is MBA in finance, operation, and marketing. All these have a good scope as compared
