The selection process for an officer in the Indian armed forces is done through a Service Selection Board (SSB) interview. Candidates who have qualified in the written examination are called for a 3/ 4 day interview and test at one of the selection boards in India.
The Selection Boards conduct a test on the first day itself which is a psychological test often referred to as the Officer Potentiality test (OPT). This test is very important as in case you flunk this test you are sent back. This test is so structured that the interviewer can gauge whether the candidate
The OPT consist of a set of questions with multiple answers. All answers are correct and there is nothing like a wrong answer. The questions are so framed that it will bring out the character of the candidate and the Interviewer will form a fair assessment of the candidate. Generally this involves answering some 50/100 question in a limited period of time of 15 minutes. There is thus no time to think and a candidate will answer as to what strikes him as true and thus a profile of the candidate
The crucial test will have some questions like what will you do if your cycle is punctured and it is raining. Will you a) sleep in bed b) Play an indoor came d) Take a trek in the rain e) Go in the shed and try and repair the cycle puncture with the kit or f) play indoor video games.
As can be seen all answers are correct. But the answer which the interviewer is looking for is as to your potential as a man with dash and initiative. Thus the more correct answer is e). I.e. Go in the shed and try and repair the cycle puncture if repair kit is available. This shows you as a positive minded person who is aggressive.
OPT frames such questions. This is the most important test and once you fail to get a minimum score the chance that you will be selected as an officer is zero. In most cases you will not be allowed to take any further tests.
The tests are comprehensive and have the backing of the Directorate of Psychological Research, Ministry of defense. Earlier these tests originated from England and were incorporated in Indian SSB.
