SYLLABUS FOR SSB INTERVIEW.

The SSB (Services Selection Board) interview process is considered one of the toughest selection processes and evaluates the candidates on various aspects to determine their suitability to join the armed forces. The process consists of two stages:

Stage I:

This includes the Officer Intelligence Rating (OIR) tests and the Picture Perception and Description Test (PPDT). Based on the combined performance in these tests, candidates are shortlisted for the next stage.

Stage II:

This stage spans over 4 days and involves Psychology Tests, Group Testing Officer Tasks, Interviews, and conferences. 

Psychology Tests:

These are conducted by a Psychologist and aim to assess the candidate’s personality including their responses to different situations. Tests include the Word Association Test, Situation Reaction Test, Self Description Test and Thematic Apperception Test.

Group Testing Officer (GTO) Tasks:

These are conducted in small groups and aim to gauge the candidate’s qualities like teamwork, decision-making, planning, and coordination. Tasks include Group Discussion, Group Planning Exercise, Progressive Group Task, Individual Obstacles, Half Group Task, Lecturette and Group Obstacle Race.

Interview:

The Interviewing Officer (IO) aims to assess the candidate’s personality, presence of mind, communication skills, leadership qualities, and knowledge during a personal interview. 

Conference:

This is the final stage where the assessing officers collectively arrive at a final assessment of the candidate based on their performance across all tests and award marks.

The entire process aims to reveal the presence or absence of Officer-Like Qualities (OLQs). Based on the final assessment, candidates are recommended or not recommended to join the Indian Armed Forces.

 EXAM PATTERN.

The NDA exam pattern consists of two written papers followed by the SSB interview rounds for shortlisted candidates. The key details of the written exam format are:

The NDA exam has two compulsory written papers – Mathematics and General Ability Test

Each paper is 2.5 hours in duration

Paper I has a maximum of 300 marks, while Paper II has a maximum of 600 marks.

Paper-I tests mathematical abilities and is objective type with multiple choice questions

Paper II evaluates English and General Knowledge skills and is an objective format with multiple-choice questions

Both papers are held on the same day according to the official exam schedule

The total marks obtained in Paper-I and Paper-II determine the candidate’s merit rank 

Based on the merit list, candidates are called for SSB interview

The SSB tests candidates’ personality, leadership skills, and mental-physical fitness over 4-5 days

Final selection depends on the combined performance in the written exam and SSB interview stage

So in summary, the NDA exam pattern consists of two objective papers testing maths, English, and general knowledge followed by an extensive personality assessment of shortlisted candidates via the SSB. The final merit list accounts for marks obtained in the written test and SSB.
