Professional engagement strategies such as networking and mock interviews can significantly boost confidence during UPSC interviews. Candidates can seek mentorship from successful aspirants or civil servants to gain insights and constructive feedback. Engaging in simulated interviews with peers or mentors helps in honing responses and reducing anxiety. Furthermore, understanding professional decorum and effectively presenting oneself contributes to a positive impression on the interview panel. This preparation builds not only knowledge but also self-assurance, crucial for performing well during the actual interview.
