##### NDA 2019 SSB Interview (Stage II)

Those candidates who qualify stage I will only be permitted to appear for Stage II. The details are as follows:

• Part I comprises of Officer Intelligence Rating (OIR) tests and the Picture Perception & Description Test (PP & DT). The candidates will be shortlisted based on the combination of their performance in their OIR Test and their PP & DT.
• Part II Comprises of the Interview session, Group Testing Officer Tasks, Psychology Tests and the last is Conference. These tests are organized over a duration of 4 days.
##### NOTE:
• The personality of a candidate is assessed by 3 different assessors viz. The IO knew as Interviewing Officer, GTO known as - Group Testing Officer and the Psychologist.
• There is no separate preference for any of the tests. The marks are allotted by the assessors only after taking into consideration the applicant's performance of the candidate holistically in all their tests.
• Marks for the conference are also allotted based on the initial performance of the candidate in the 3 techniques and decision of the Board. All the tests have equal preference.
