What is an Interview? It is the process of selling of the candidate
to the particular organization.

 The Personal interview (PI) may also be taken as a purposeful conversation between a candidate and the interviewing officer(IO) to check out the particular pre-determined qualities(OLQ).

 Personal Interview:- The PI is the psychological assessment of the candidate by the the IO usually in the rank of colonel i.e. who is the president or deputy president of the board.

The IO reads well the PIQ filled by the candidate on the first day
The IO just cross check the candidate by triggering some basic questions,
and also triggering the series of questions at a stretch that is called as Rapid Fire Questions . With these replies he note down the response and check the candidate whether he is truth ful with his answers and also he note down the OLQ of the candidate.

 So nothing to worry about the PI, just be calm and march with good preparation, then it will be easy to crack the process.

 How to be cool in the whole process:- To make the whole process as a cake walk, the only way is to be honest and truthful. Since it is not easy an easy task to tel a lie or bluff to the IO. As he is very much trained to catch the liers and everyday he is facing
numerous persons telling lies. The simple quote about selection process is "BE YOURSELF" since if we are truthful to the IO, then we will tell our answer boldly and confidently. The IO also expect the same from the candidates. So we wont bluff and never stammer in our answer. So better improve the qualities and social adaptability of the self to be a better citizen and good officer. If we improve and train our self for the development of the officer like qualities, the PI will be cool.

Also, what the inerviewing officer expect from the candidate is not be an all rounder or a well knowledged person, but a person who adapts to all situations can handle and work under
pressure, can able to move with a group of people, have an eye over the world and
national issues, can be able to give solution to the national issues etc. So put yourself to these points and assess yourself.
