Hello Meghna,
I am a student pursuing MBA in HR, I would like to clear your query:-
HR's Job...in almost all the sectors and industries, may it be services, it, telecom, or manufacturing, or any type of setup.
the profiles are varied from recruitment, employee relation, comp & reward management, performance development etc.
At present there are many consultancies coming up, which provide with great opportunities for fresh hr professionals.
Now about MBA in finance...these people are generally paid more, recruitted quickly, are promoted quickly (all these compared to HR prof.)...but all this comes with a hunger of number crunching, huge amount of data analysis, quiet into stocks, shares, derivatives etc.
At end I would just like to say, what ever you choose you have to live with that decision for life long..so choose carefully...choose what you can do for whole of your life.
