Practices to improve public speaking in mock interviews include regular practice, recording sessions for self-assessment, and seeking feedback from peers or mentors. Rehearsing responses aloud builds confidence and helps with articulation under pressure. Joining public speaking forums or workshops can provide constructive practice environments and expose aspirants to diverse perspectives. Learning body language and effective non-verbal communication techniques are equally crucial. Lastly, focusing on clarity and coherence in speech enhances overall presentation skills, preparing candidates for potential questions during real interviews.
