The officers of all India services were initially selected by UPSC. This practice was amended for BARC then ISRO and then DRDO. The reason was given that the UPSC delayed the selection process and the demand of scientific agencies was not met in time. May be honorable Late prime minister Mrs Indira Gandhi was convinced with the demand of BARC and ISRO as chairman of Atomic Energy and Space Commission. BARC and ISRO with full honesty implemented the recruitment rules of government of India. However, in the case of DRDO a carbon copy of that rule was followed, the carbon powder smeared out the essential and desired qualifications. And a result these days the officer sitting at the helm of affairs are second class graduates/post graduates who joined as JSA, SSA and charge man. The technical officers QR even for the ARMY/NAVY/AIRFORCE demands of choice is first class graduates/post graduates, but the premier DRDO is having 60% of its manpower with lower qualifications
Even if they recruit 1st class graduates with background from IITs, they have to work with persons who do not possess the relevant degree. There is an opinion that the experience has added advantage to those who are less qualified.
In fact these people sitting helm of affairs create hindrance on the areas of national interest because of less knowledge and ego. They try to train them how to bluff, create bluff and live life as bluffer. This resulted as brain drain from DRDO. The youngsters feel humiliated, their future appears bleak and they are forced either follow the footsteps of bluffers or leave the organisation. Just go through the data of DRDO that how many scientists resigned in last 20 years. It is alarming.
