Improving public speaking skills for the UPSC interview involves several strategies. Firstly, practice is vital; participating in mock interviews helps build confidence and familiarity with the format. Candidates should focus on clear articulation of thoughts and maintain a steady pace. Engaging in regular public speaking or joining clubs like Toastmasters can enhance delivery skills. Additionally, recording practice sessions allows candidates to self-evaluate and identify areas for improvement. Understanding body language and maintaining eye contact are crucial for creating a positive impression. Lastly, preparing succinct answers to potential questions enhances both clarity and confidence during the actual interview.
