He said a communique has been sent to all state governments, state public service commission and Staff Selection Commission to identify posts where interviews can be discontinued.
The move comes a fortnight after Prime Minister Narendra Modi put forward such a suggestion during his Independence Day address to the nation.
Singh, Minister of State for Personnel, reiterated the Prime Minister's claim that interviews sometimes lead to "manipulation, maneuverability and corruption".
"Therefore, barring such posts where an interview would help in testing special capabilities for a particular assignment; abolition of the provision of interview will not only be in larger public interest but would also offer a level playing field, even for those candidates who are resourceless and belong to lower socio-economic strata," he said.
