IES Stage III (Personality Test):

The interview is one of the most important parts of the exam. It is important for you to clearly state your thoughts to the interviewers.

So focus on brightening your communication skills and body language. Some candidates are blessed with such skills.

Some require practice to become excellent communicators of their ideas. Candidates with no communication skills can contact those who have already appeared in the Civil Services Examinations, to get useful suggestions from them.

The interview portion of the Civil Services Examination is not designed to judge someone’s expertise on a subject.

However, a candidate must speak from the heart or answer all questions honestly.

There is a common misconception among the candidates that if they lie about their hobby just to get through the interview, it will never help them.

Interviewers are not just to ask questions, but to evaluate a candidate’s personality and ability to evaluate whether a ‘no’ is a ‘no’, it cannot be changed to a ‘yes’ and vice versa.
