The UPSC selection process promotes meritocracy by evaluating candidates based on a standardized examination system, which includes preliminary, mains, and interview stages. Each stage tests knowledge, analytical skills, and personality traits, ensuring a comprehensive assessment. The transparent nature of the process, alongside published examination patterns and cutoffs, fosters an environment where qualified candidates can succeed based on their performance. This merit-based approach helps in identifying individuals who are not only academically competent but also possess the qualities required for a successful bureaucratic career.
