After clearing the NDA written exam, the next and most important stage is the SSB Interview. The SSB (Services Selection Board) is a five-day evaluation process designed to assess a candidate’s Officer-Like Qualities (OLQs). These qualities determine whether you have the personality, leadership, communication skills, and decision-making ability required to become an officer in the Indian Armed Forces.

This detailed guide explains each stage of the NDA SSB Interview including OIR, PPDT, GTO tasks, command tasks, personal interview, and conference. You will also learn important preparation strategies to help you perform confidently.
