NDA SSB and CDS SSB Selection Ratio
NDA SSB and CDS SSB Interviews are the toughest among all the interviews conducted for Government Jobs. Many candidates have the potential to clear the NDA and CDS written exam but have failed multiple times in the SSB Interviews. Thus, it is better to start your preparations under expert guidance at BYJU’s Exam Prep.
Many candidates face rejection on Day1 of the selection process itself and are declared disqualified in the process. The rate of selection is just 6 to 10 percent in the NDA SSB Interview. The final selection in the CDS SSB Interview is even less at 5 to 6 percent.
Even at stage 1 of SSB Interview, OIR Test, and PPDT, SSB aims to clear out 60 percent of the shortlisted candidates from the written examination.
Good Luck!
