It is not a question about whether or not BM is bad, and HR is good. XLRI is more known for HR because it has stuck with the brand. The brand XLRI primarily had an established legacy in Industrial Relations (IR). Which later converted into HR. XLRI established its reputation as an IR concentrated institution following the Independence of the country.
BM, on the other hand, was inaugurated only afterward alongside older IIMs. This has somehow resulted in leading to the XLRI brand getting generally and mostly associated with HR, and not BM. It’s rare to find any industry or top-tier companies in the country where the top HR personnel is not from XLRI.
Now when talking about BM at XLRI, there is definitely a strong and successful alumni base from BM in the industrial sector. In fact, for further recruitments, alumni of XLRI get placed in McK, BCG, and several more from the BM sector.
