Extracurricular experience is crucial in bolstering UPSC interview applications because it showcases a candidate's well-rounded personality and diverse interests. Participation in activities such as volunteering, leadership roles, or sports reflects qualities like commitment, teamwork, and social responsibility. Such experiences can provide relevant examples during interviews, demonstrating how candidates apply theoretical knowledge to real-world contexts. They also contribute to developing essential soft skills, making candidates more appealing to the interview panel, which increasingly values holistic profiles.
