I appeared in an interview at SVNIT Surat to renew my contract as Teaching Assistant(TA). An interviewer asked me to enlist experiments conducted in laboratory. I did not remember because it was long time ago. It provoked a thought in my mind, what to check in an interview?
Of least interest, it is simplest thing comes in interviewer’s mind to check because our exams from class one checks memory and writing ability in three hours. This type of evaluation is important at primary level or middle level of career e.g. alphabets need to be remembered up to 10th standard while it should not be repeated in a PhD interview.
It is required when person is required for multitasking e.g. civil service aspirant need to have information about liquid propulsion rockets but not necessarily have knowledge of combustion kinetics involved in combustion chamber. In simple words, overview of a subject.
Knowledge need to be checked while interviewing top level posts. Knowledge is obtained after conducting experiments followed by analysing results. Knowledge is net output after experiment/theory, data interpretations, observations, conclusions. It requires greater efforts to acquire knowledge. Consider case of Alan Turin who invented a machine which can decode messages intercepted, which were sent from a machine named Enigma placed at German army’s headquarter to troops located at battlefields. That machine, known as Turin Machine, is considered as pioneer of modern computers. True interviewer knows what to ask to different level of candidates. While interviewing PhD knowledge has to be checked rather than memory and information.
