NDA SSB vs CDS SSB: Every year, lakhs of students appear for NDA and CDS written examinations. Out of them, only a few thousand are selected for the SSB Interview. Most of the time, students are not fully aware of the SSB interview process. This leads to failure as one may be intelligent in academics, but do not have required personality traits like Intelligence Quotient (IQ), Presence of mind, and confidence, which can only be gained through practice.

What is SSB Interview?

Service Selection Board (SSB) Interview is a process to filter out the candidates who fit best for the job. SSB does not mean that those candidates who are not recommended are a failure in life, but it only means that they are not fit to be an Officer or do not have Officers-like qualities.

SSB Interview is conducted for both NDA and CDS entries, the main difference in the level of expectations from a candidate. Let’s discuss what are some similarities and differences between the NDA SSB Interview and the CDS SSB Interview.

Chances of Selection in NDA and CDSE SSB Interview

Frankly speaking, the chances of selection in NDA are far more robust than that of the CDSE. There are two major reasons for that:

1. The rejection levels are high in CDSE because according to SSB, the graduate-level entries can only be recommended if the candidate is perfect in all sense.

The SSB expects that the candidate taken through the CDSE examination should in a tailor-made officer material already and in the 5-6 day interview, they just look for all such traits in his/her personality. As the scope of correction is very less after the selection, so they do not take any chance while selecting the CDSE candidates. 

If any NDA candidate shows a little spark, the chances of selection become high. It is because a young person is trainable if he has good qualities if not the exceptional ones. But a person nearly steeping in adulthood is difficult to be trained to change his traits. 

2. The vacancies in CDSE are very less compared to NDA. This difference in the selection ratio is also a major counting factor. In the CDS SSB batch, in one batch of 100 persons, on average, only 2-5 are selected. 

Though the value is not fixed, generally, it is so. There may be a chance that more candidates are selected or no candidate is selected at all.
