My NMAT score is 222 and I am eligible for XIMB HRM. Should I join XIMB HRM having 30 months work experience in L&T?

Yes, you can easily get into XIMB HRM with your NMAT score. In Fact, there are many other B Schools that accept NMAT scores like

The colleges in order of their ratings are-

• NMIMS Mumbai (212 and above)
• NMIMS Bangalore (199 above)
• NMIMS Hyderabad (190–195)
• XIMB (190–200)
• NMIMS Navi Mumbai (185+)

Honestly, only NMIMS Mumbai and Bangalore are worth investing in. 

One can certainly apply for the exam again but they must bear in mind that the cost of the exam is costly and you will have to apply separately and fill out forms for the exam as well as colleges again.

NMIMS Mumbai lays great emphasis on your work experience So, even with an average performance in CDPI one can convert a call.

NMIMS Mumbai enjoys a locational advantage being located in the finance and business hub of the country. It is among the 15 top B schools in the country
