The timeline for the UPSC Civil Services Examination process spans several months, starting from the notification, followed by the Preliminary, Mains, and interview stages. Typically, the notification is released around February, with the Preliminary conducted in June. Results are announced in July, leading to the Mains in September/October. Candidates who qualify are interviewed in early next year, with final results declared by March/April. This extended timeline requires aspirants to plan meticulously, allowing adequate preparation time for each stage while maintaining consistent progress throughout the year.
