SSB Interview Process - Intelligence and Personality Test

The SSB procedure consists of a two-stage Selection process - stage I and stage II. Only those candidates who clear stage I are permitted to appear for stage II. The details are :

(a) Stage I comprises of Officer Intelligence Rating (OIR) tests are Picture Perception * Description Test (PP&DT). The candidates will be shortlisted based on the combination of performance in the OIR Test and PP&DT.

(b) Stage II Comprises of Interviews, Group Testing Officer Tasks, Psychology Tests and the Conference. These tests are conducted over 5 days. The details of these tests are given on the website - joinindianarmy.nic.in.

The personality of a candidate is assessed by three different assessors viz. The Interviewing Officer (IO), Group Testing Officer (GTO) and the Psychologist. There is no separate weightage for each test. The marks are allotted by assessors only after taking into consideration the performance of the candidate holistically in all the tests. In addition, marks for Conference are also allotted based on the initial performance of the Candidate in the three techniques and decisions of the Board. All these have equal weightage.

The various tests of IO, GTO, and Psych are designed to bring out the presence/absence of Officer Like Qualities and their trainability in a candidate. Accordingly, candidates are Recommended or Not Recommended at the SSB.
