recruitement is done through a competitive exam which tests the candidate's grasp on the academics. The interview process is deemed to be on the basis of the research work done but in practice its more dependent on the whims and fancies of the chairperson of the board. The system of fast track recruitment from premier colleges (only IIT's and central universities) excludes good private colleges (like BITS Pilani). Also it is a method for recruiting undeserving wards of senior scientists of the organisation.
