You may be right but if you have choosed HR Profession, I think you did the right choice. When you looked behind in the 1980, there was no concept of HR but now you will feel every good company prefer to develop the HR department becoz they understand without having a strong HR Department firm can be achieve its goals. I am also doing MBA in HR with bye major in Finance. I am only one in the class who chose HR and I am confident that I will make a place in the market.
Dont worry, just go ahead on your mission. God bless.
