UPSC NDA Intelligence and Personality Test
The SSB procedure comprises two stages selection process  stage I and stage II. Candidates who will ace stage I are allowed to participate in stage II. The details are:
 Stage I comprises Officer Intelligence Rating (OIR) tests are Picture Perception Description Test (PP&DT). The candidates will be shortlisted based on a combination of performance in the OIR Test and PP&DT.
 Stage II Comprises Interviews, Group Testing Officer Tasks, Psychology Tests, and the Conference. These tests will be held over 4 days. The details of these tests will be notified on the official website.
The personality of a candidate is judged by three different assessors viz. The Interviewing Officer (IO), Group Testing Officer (GTO), and the Psychologist. There is no separate mark weightage for each test. The marks are given by assessors only after analyzing the performance of the candidate holistically in all the tests. In addition, marks for Conference are also assigned based on the initial performance of the candidates in the three techniques and the board’s decision. All these are given equal weightage.
We hope this article was insightful for all the candidates. The candidates must get familiar with the UPSC NDA Syllabus and exam pattern before commencing their preparation to focus well on the important topics of the exam.
