The final stage is that of interview. There are cases where students clear the preliminary and the mains but fail at the last stage. The secret is to start for preparations for the interview along with the written test. Develop the habit of debating and discussing issues with friends or parents. Listen to the current affairs programmes and learn to organise thoughts the way the participants do. Develop interests and hobbies so that you are able to answer convincingly. Understand the current affairs and the issues behind the events. Remember that the interview is not a cross examination but a natural but purposeful conversation. It is an opportunity to reveal the mental qualities of a candidate.
The interview is not a test of specialised knowledge, as that has already been tested in written examination. The idea is to see the social traits of a person and his personality as suited to a career in the Civil Services. If a person gives the impression of being a bookworm, the chances of his selection are reduced. The candidate must exhibit an intelligent interest in events happening around him so that he appears to be a complete personality.
Finally, there is a very frequently asked question about whether a candidate should join a coaching centre and if so, which one. Coaching centres are helpful in the sense that they develop a discipline of attending regular classes. An instructor may be available who can give an opinion about the answers written by a candidate. At the same time, the candidate will meet like-minded people with whom he can develop the habit of debating and discussion. However, the coaching centre must be chosen with care: the instructor must be erudite enough to be able to guide students. If he is not well read, the chances of guiding others would be diminished.
It must also be remembered that preparation for the optional subjects must be done on one's own, as it is unlikely that any coaching centre would be able to do justice to all the subjects.
