Public speaking practice is highly beneficial for UPSC interviews. It enhances candidates' communication skills, making them more articulate and confident in expressing their thoughts. Regular exposure to speaking in front of an audience reduces nervousness associated with interviews. This practice allows candidates to refine their ability to structure responses clearly and succinctly. Moreover, honing body language and presence is vital in making a strong impression. Engaging in mock interviews also equips aspirants to handle unexpected questions effectively, thus improving adaptability and quick thinking during the actual interview.
