I aslo had received the "Interview Call Letter" 3 days before and it was mentioned in the letter that my said interview is as on 29-01-2016 but today i again got a call from OGDCL that now my interview date have been changed to 27th jan...whats going on?

first they issued direct interview letters then they cancelled them by saying that written test would conducted first, again they cancelled the said test and now again interview letter without taking test? it leaves OGDCL dubious and cunning....i don't think they will follow any merit.
