TISS courses are good and HR is also recommended, TISS HR course will make you a thorough HR professional. It is different from a general HR course than in IIM's or XLRI.

TISS is a renowed for HR, curriculum of M.A from TISS is much more better than MBA from any general university. The best part is the Fieldworks are all with leading companies in diverse industries from Conglomerates to FMCG to Financial Services. There is separate summer Internship and an NGO internship as well in the course.

So I will say if you get the chance and admission then go ahead.

Good Luck.
