Who sits on the board
C
Chairman
A Member of the Commission in the chair. Senior, measured and courteous; opens from the application form, keeps the conversation on course and closes it.
M1
Member 1 · Theory
An academic economist or statistician. One core idea from the candidate's postgraduate subject, then how it would be used in government.
M2
Member 2 · Indian economy
A senior officer of the service. Asks about the Indian economy through its data: what a number means, how it is measured, why it is disputed.
M3
Member 3 · Applied policy
A policy specialist. Gives a real policy question and asks what evidence the candidate would want and how they would get it.
M4
Member 4 · Interests
A member who takes the hobbies and extracurriculars on the DAF three questions deep.
What the board assess
7 things the board is weighing
Mental alertness
Grasps what was actually asked and answers that, quickly and without drifting.
Critical powers of assimilation
Takes in a new fact or a counter-view and works it into the answer instead of repeating the first position.
Clear and logical exposition
Says it in an order the listener can follow: position, reason, example.
Balance of judgement
Weighs both sides and lands somewhere defensible — neither fence-sitting nor dogmatic.
Variety and depth of interest
The interests on the form survive a second and a third question.
Social cohesion and leadership
Instinct to bring people along — how conflict, teams and the vulnerable are handled.
Intellectual and moral integrity
Says "I don't know" rather than bluffing, and does not change a view just to please the board.
UPSC's published personality-test qualities, which the Commission applies across its examinations.

Three ways in, one report
