The Services Selection Board (SSB) is one of the toughest military selection systems in the world, which ensures that only the best candidates are chosen to become officers in the Indian Armed Forces. 

Whether you are appearing for the CDS 2025 SSB interview, NDA SSB, or AFCAT SSB, the process remains highly competitive, with only 5-10% of candidates getting recommended each year.


The SSB selection procedure is not just an interview; it’s a five-day scientific evaluation that tests your intelligence, leadership skills, personality, physical stamina, and psychological strength. 

This blog explains the SSB interview process step by step so you know exactly what to expect and how to prepare.
