My interaction with you so far on this thread, Sandip, confirms the above observation of our learned friend Mr.Venu. Assumptions and presumptions have place only in gray areas. There is nothing unclear in this situation - At the time of applying for the job, you had to route your application through proper channel which you did. Now, you are called for an interview with an NOC only in case you did not submit your application thru proper channel. You have a confusion about this NOC because of the change in your job in the mean time and hence you approached your present employer for an NOC which was turned down based on the existing practice followed in CPUs in general. How you anticipate that your leave application would be rejected if you mention the interview purpose? Rejection of NOC is different based on its reason.
