Candidates can prepare for unforeseen questions in the UPSC interview by engaging in regular mock interviews and simulation exercises. Developing a broad knowledge base across subjects allows for more agile responses. Additionally, practicing impromptu speaking activities can enhance quick-thinking skills. Being updated with current affairs and connecting them to static knowledge enhances a candidate’s adaptability. Reflecting on common interview themes—like ethical dilemmas or social issues—further prepares candidates to handle unexpected questions gracefully, showcasing their analytical and critical thinking capabilities.
