⚠️ Why Application Forms Get Rejected (The 2026 Reality)

Every year, over 15% of government recruitment applications across the Staff Selection Commission (SSC), Union Public Service Commission (UPSC), Railway Recruitment Boards (RRB), and State Police recruitments are summarily rejected during preliminary scrutiny. The primary culprit is rarely educational ineligibility—it is non-compliance with digital photograph and signature upload specifications.

Modern recruitment systems employ automated computer-vision algorithms to validate aspect ratios, pixel density, facial symmetry, and file header sizes. If your uploaded image is blurry, stretched, or exceeds the specified byte ceiling by even 1 KB, the portal either rejects submission or marks your candidature for cancellation during Document Verification (DV).
