It is true that UPSC/DOPT does not typically contact any previous private employers of candidates when they clear the UPSC CSE Exam as part of background verification.

Yes, that is generally correct. The Union Public Service Commission (UPSC) and the Department of Personnel and Training (DoPT) do not typically contact previous private employers for background verification during the clearance process for candidates who have passed the Civil Services Examination (CSE). The emphasis is usually on verifying the information provided in the application forms and checking any relevant government records. However, specific practices can vary, and it's always advisable for candidates to provide accurate and truthful information in their applications.
