All those candidates who clear the cutoff in the written exam are called for SSB interview for further evaluation. The complete SSB interview process takes 5 days. Selected candidates are called in different SSB centers for a maximum of 5 days.
The SSB Interview is divided into two stages. Candidates qualifying the Stage 1 are called for Stage 2 exam. Stage 1 of SSB Interview comprises Officer Intelligence Rating (OIR) tests and Picture Perception and Description Test (PP&DT). Stage 2 comprises Group Testing Officer Tasks, Psychology Tests, and the Conference. This stage carries a total of 900 marks.
The twostage process for NDA SSB Interview is as follows:

NDA Medical Test Process
All the SSB recommended candidates are then requested to appear before the medical board for a complete medical checkup. Medical tests can take 4 to 5 days to get completed. Only after the medical board declares a candidate fit then only they are recommended. If any candidate is declared unfit then he cannot join the academy but can file a review for his other medical checkup.
