UPSC Syllabus for IAS Mains
The UPSC Mains Exam is a crucial part of the Civil Services Exam because every mark scored in this stage counts for the selection process. The UPSC Mains Syllabus is designed in a way that helps in assessing the academic talent of the individual in form of her ability to apply and present her knowledge. Rather than memorisation and regurgitation (aka ratta-fication) the exam is designed to analyse overall understanding of the subject and depth of intellect.
It consists of 9 subjective type papers, out of which 2 are qualifying papers carrying 300 marks and remaining are 250 marks each (total of 1750 marks). Only the marks obtained by the candidates for the Paper-I-VII will be counted for merit ranking.

UPSC Syllabus for IAS Interview
The candidates successfully qualifying the UPSC Mains Exam are then moved to the final phase of the process i.e. Personality Test or Interview carrying 275 marks. The test is conducted by the Board of competent that checks the personal aptness of the appearing candidate. The performance of the each candidate is evaluated on the basis of mental alertness, judgement, leadership skills, etc.
·         The candidate will be interviewed by a Board who will have before them a record of his/her career. He/she will be asked questions on matters of general interest. The object of the interview is to assess the personal suitability of the candidate for a career in public service by a Board of competent and unbiased observers. The test is intended to judge the mental calibre of a candidate. In broad terms this is really an assessment of not only his/her intellectual qualities but also social traits and his/her interest in current affairs. Some of 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 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.
·         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.

Lastly, the final merit list is issued on the basis of the marks scored by the qualifying candidates and the list is published in the leading newspapers to notify the successful candidates.
