Competitive mock interviews play a pivotal role in UPSC preparation by simulating the real interview environment. They allow candidates to practice responses, receive constructive feedback, and improve their communication skills. Exposure to diverse questions fosters critical thinking and enhances confidence, while practice hones the ability to articulate thoughts effectively. Mock interviews also help identify areas of improvement, such as body language and tone, which are crucial for creating a positive impression on the interview board. Overall, these sessions contribute significantly to a candidate's preparedness, making them more equipped to face the actual interview.
