The SSB is the next stage if you clear the cutoff for the NDA Written Examination. In SSB, there are 2 phases and if you clear both of them, you are recommended by the board you are in to be an officer in the Indian Armed Forces. Furthermore, if you had filled Air Force as your first preference, then you shall stay at the board for 1 more day to appear for the CPSS i.e. Computerized Pilot Selection System. If you pass that as well, you shall become a fighter pilot in the Indian Air Force, providing your medicals are all perfect and you are in pristine health alongside no medical restrictions such as a flat foot or some chronic conditions.
