Aspirants can explore cultural narratives for the UPSC interview by engaging with diverse forms of art, literature, and history. They should immerse themselves in regional stories that reflect the diversity of Indian culture, as this will provide them with unique perspectives to discuss in interviews. Joining community forums, reading biographies, and attending cultural events can enhance their understanding. Additionally, documenting personal experiences and connecting them to broader cultural themes can demonstrate depth and authenticity, allowing candidates to articulate their viewpoints effectively during interviews.
