It serves as the gateway for young, unmarried male and female candidates to join the Indian Army, Navy, and Air Force. The selection process is bifurcated into two rigorous stages: a written examination consisting of objective-type questions and a five-day Service Selection Board (SSB) interview, which evaluates the candidate’s officer-like qualities (OLQs), psychological aptitude, and physical fitness.
