The UPSC evaluates ethical and integrity standards in candidates during the interview by observing their responses, behavior, and overall demeanor. Scenarios presented during the interview often focus on ethical dilemmas faced in public service, assessing candidates' decision-making capability and moral reasoning. The panel looks for qualities like honesty, accountability, and a commitment to public welfare. Candidates are also evaluated on their understanding of the Code of Conduct and how they would uphold these principles in real-world situations, forming a crucial part of the selection process.
