"Authorities should do away with the system of interviews to offset the chances for favouritism and irregularities," CPI(M) state secretary Mohammad Yousuf Tarigami said in a statement.
His comments came after two unsuccessful civil services' candidates alleged that interview marks were manipulated to favour relatives and acquaintances of the commission members.
Jammu and Kashmir Public Service Commission (PSC) termed the allegations as "baseless" but said they are considering video-recording of interviews in order to bring transparency in the process.
Tarigami, however, said well structured objective tests will leave no scope for "bias or prejucide". He said videographing of interviews would not also serve the purpose of bringing transparency.
"Interviews constitute unnecessary interference in the selection process," he said.
