The Interview: The Vital Part of the NDA Exam

Once you pass the written test, you will be called for the interview. The interview process is also as rigorous as the written test. This is one of the important aspects of the NDA exam pattern.

The NDA interview is known as the SSB interview as it is conducted by the Service Selection Board. The NDA SSB Interview is conducted in two stages - Stage 1 & 2. Those qualifying the 1st stage of the interview will be called for the second stage. 


Stage 1

Within Stage 1 of the NDA Interview, there will be a screening test and a PPDT test. The screening test will consist of verbal and non-verbal tests which are not that hard. The questions in the screening test will include - make sentences, correct the spelling, which of the following words comes last in the dictionary etc. 

In the PPDT test , you will be shown a picture for 30 seconds and then you will be asked to write about that picture within 3 minutes. Later, you will find that the candidates are divided into groups. You have to talk and discuss the picture and your story along with others.

The PPDT test will be followed by a Psychological Test in Stage 1.  The psychological tests will be divided into several stages - 

  • Thematic Apperception Test - This is similar to the picture test described above - only harder and intense.

  • Word Association Test - This is similar to a picture test, but the pictures are replaced by words.

  • Situation Reaction Test - In this test, you will be presented with some situations and then you have to write about your responses to these situations.

  • Self Description Test - In this test, you have to talk about yourself, your personal life etc.


Stage 2

Based on the screening test, candidates will be selected for Stage 2 of the interview process and some will have to bid goodbye.

In Stage 2, there will be a Group Testing Officers Test or the GTO test. The GTO test also has multiple steps

  • Group Discussion

  • Group Planning

  • Progressive Group Task

  • Half Group Task

  • Individual Obstacles Task

  • Command Task

  • Snake Race

  • Individual Lecture

  • Final Group Task


Personal Interview and Conference

Then there will be a vital personal interview following the GTO in Stage 2. You will be facing an IO or Interviewing officer and you have to maintain a strict code of conduct and answer questions tactically, logically and intelligently. From personal questions to political discussions, from psychological questions to general intelligence questions - nothing will be spared. Honesty, agility and sincerity are the keywords here.

The personal interview round will finally be followed by a conference round.
