During UPSC interviews, panelists evaluate candidates' attitudes and values through a combination of questioning and observation. They assess candidates' responses for confidence, honesty, and consistency in their viewpoints. Emphasis is placed on the manner of speaking, including body language and facial expressions. Additionally, panelists look for a candidate's understanding of current events and their alignment with core values like integrity and social responsibility. A well-rounded perspective and the ability to articulate thoughts clearly showcase a candidate's maturity and preparedness for the role.
