Complete Guide to CDS 2027 Selection Process

The CDS 2027 selection process conducted by the Union Public Service Commission (UPSC) comprises a rigorous two-stage approach: a competitive written examination followed by the Services Selection Board (SSB) interview. Candidates must clear the written cutoff and physical standards before undergoing a comprehensive five-day personality and intelligence assessment for final induction.

What is the Exam?

The Combined Defence Services (CDS) examination is one of India's most prestigious gateways to becoming a commissioned officer in the Indian Armed Forces. Conducted twice annually by the UPSC, the examination facilitates recruitment for the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers Training Academy (OTA).

We at Exam Bhai define this exam not just as a test of academic knowledge, but as a holistic filter designed to identify leadership, mental alertness, and psychological stability. The process is highly competitive, and understanding the nuances of the selection stages is the first step toward securing a seat at these premier defense training institutions.
