Candidates who have qualified in the Civil Services Main Examination will be called for the final stage of the selection process, i.e., Personality Test (Interview). It will carry a total of 275 marks. The number of candidates will be called shortlisted for an interview is twice the number of vacancies. The board will test the candidates on various areas starting from his/her career to general interest.

The assessment will be on the intellectual qualities along with their social traits and his interests in current affairs. It will also assess the candidate's mental caliber. The qualities to be judged are mental alertness, critical powers of assimilation, clear and logical exposition, balance of judgement, variety and depth of interest, ability for social cohesion and leadership, intellectual and moral integrity.

The official CSE notification reads, “The technique of the interview is not that of a strict cross-examination but of a natural, though directed and purposive conversation which is intended to reveal the mental qualities of the candidate.”

It also added, “The interview test is not intended to be a test either of the specialised or general knowledge of the candidates which has been already tested through their written papers. Candidates are expected to have taken an intelligent interest not only in their special subjects of academic study but also in the events which are happening around them both within and outside their own State or Country as well as in modern currents of thought and in new discoveries which should rouse the curiosity of well-educated youth.”

Note: There is no specific syllabus for IAS Interview, hence, we advise candidates to work more on their personality. The final merit will be based on marks obtained in the Main Examination and Personality Test.
