What is the Exam?
The Combined Defence Services (CDS) Examination is a prestigious national-level recruitment process conducted by the Union Public Service Commission (UPSC). We at Exam Bhai view this as the primary gateway for ambitious graduates to serve as commissioned officers in the Indian Army, Indian Navy, and Indian Air Force. The exam is held twice a year, offering two distinct cycles for candidates to showcase their officer-like qualities (OLQs) and academic prowess through a written test followed by the rigorous Services Selection Board (SSB) interview process.
