Emotional intelligence (EI) is crucial in the UPSC selection process as it encompasses the ability to understand and manage one's own emotions and the emotions of others. High EI can help candidates handle the pressure of examinations and interviews better, allowing for clearer communication and effective conflict resolution. It fosters empathy, which is vital for civil servants who must engage with diverse populations. Candidates with strong EI are adept at building interpersonal relationships, which is essential for collaborative governance and addressing community issues in their future roles.
