🎯 The Selection Journey

Cracking the exam requires passing a three-tiered assessment hierarchy: [18, 19]

  1. Written Examination: Achieving the minimum qualifying cut-off score set by UPSC.
  2. SSB Interview: Shortlisted individuals undergo a intensive 5-day intelligence and personality evaluation consisting of psychological tests, group tasks, and personal interviews.
  3. Medical Examination: A stringent medical board check ensures top-tier physical conditioning. [2, 3, 10, 20, 21]

Upon successfully clearing the final merit list, cadets undergo training at their respective academies and are commissioned with the initial rank of Lieutenant (or equivalent) with a starting basic salary of ₹56,100. [2, 3]
