2. Services Selection Board (SSB) Interview
The SSB interview is a five-day selection process conducted at various SSB centers across India. It assesses candidates on their officer-like qualities (OLQs) through psychological tests, group discussions, and outdoor activities.
Day 1: Screening Test
Officer Intelligence Rating (OIR) Test – Verbal & Non-verbal reasoning questions.
Picture Perception & Description Test (PPDT) – Candidates write a story based on a given picture and participate in a group discussion.
