Hi,
I don't think that any other certification will help you to get a job. Since you are pursuing an MBA, it is a sufficient educational qualification for an entry-level position. However, there is always room for learning through experience.
I suggest you concentrate on your course and successfully complete it. After that, consider working for a small organization or a recruitment consultancy to gain some experience. There will be significant opportunities in India once the recession is over, especially in the new HR dimension - Delivery HR. To excel in this field, you need to have a good understanding of HR processes, which cannot be acquired solely through a certificate. So, move forward and enjoy your current studies.
