UPSC verifies the integrity of information provided by candidates through rigorous background checks and disqualifications for discrepancies. This verification process includes cross-referencing documents and conducting interviews for specific cases. Ensuring the authenticity of educational qualifications, age, and identity is critical in maintaining the credibility of the examination system. Candidates found to have provided misleading information risk facing severe consequences, including cancellation of results or disqualification from the selection process, reinforcing the importance of honesty during application.
