NOTE I: Paper I will be Objective type multiple choice.
NOTE II: Paper II will be of conventional type.
NOTE III: Paper I and II will be bi-lingual (i.e. in Hindi and English). Candidates will have option to
answer Paper II either in Hindi or in English language.
NOTE IV: Paper II will be evaluated in respect of only those candidates who qualify in Paper I at the
minimum standard which may be decided by the Commission at its discretion.
NOTE V: Only those candidates who attain minimum qualifying standard in Part-I of the
Examination, as may be fixed by the Commission in their discretion, will be eligible to be
called for Personality Test/Interview.
B. Part II: Personality Test (Interview): 100 marks
The interview/personality test is structured in such a manner that the candidates’ interest,
knowledge, various traits, aptitude, suitability etc. are probed among other things, through academic
qualifications, experience, extra-curricular activities, general awareness/knowledge, depth of
knowledge of the subjects studied (10+2 onwards), communicative skill and over-all personality etc.
Candidates called for interview/personality test, have the option to converse either in Hindi or
English language during the interview process.
Syllabus:
The standard of the questions in Engineering subjects will be approximately on the level of Diploma
in Engineering (Civil/ Electrical/ Mechanical) from a recognized Institute, Board or University and
recognized by All India Board of Technical Education. All the questions will be set in SI units.
1. General Awareness:
Questions will be aimed at testing the candidate’s general awareness of the environment
around him and its application to society. Questions will also be designed to test knowledge
of current events and of such matters of everyday observations and experience in their
scientific aspect as may be expected of any educated person. The test will also include
questions relating to India and its neighboring countries especially pertaining to Sport,
History, Culture, Geography, Economic Scene, General Polity, Indian Constitution and
Scientific Research, etc. These questions will be such that they do not require a special study
of any discipline.
