Mock interviews simulate real scenarios for UPSC candidates by creating a realistic environment similar to the actual interview. This practice helps aspirants become comfortable under pressure, honing their communication skills and quick thinking. By receiving feedback from experienced panelists or peers, candidates can identify areas needing improvement, such as clarity of thought or articulation. It also allows them to practice common questions and develop strategies for unexpected queries. The experience gained through mock interviews enhances confidence and prepares candidates to navigate nuanced discussions during the actual interview, increasing their chances of success.
