2-year MBAs are considered better than 1-year long PGDHRM. But if you are a working professional and you need a flexible course, SIBM Bangalore 1-year PGDHRM is a good option. You will get decent exposure and networking opportunities. For this course, placements aren’t provided by the institute. But students get good job offers through off-campus placements.
This depends upon what you are looking for. If you are currently in your final year of graduation and the only option you have is SIBM Bangalore, then you can take the exam next year. As you have the time and resources.
However, if you are a working professional with over 1 to 1.5 years of work experience, then you possibly should avail the offer. Because preparing again might or might not provide you with a better option than a 1-year program.
Needless to say, SIBM Bangalore is well renowned for its finance and operation profiles. But, the HRM profile can relevantly also turn out to be disadvantageous, as you will have to find placements on your own.
If you are however interested in HR, then you can apply at TISS, or XLRI because they have one of the best HR programs in the country.
