I think there should be no need of group discussion as it was not mentioned in the advertisement and also its not the mto post....there should be interview directly....by the way honestly speaking that its useless to hope anything good from bok as there is no merit to be followed due to corruption and the biggest example of it was the mto program of 2012 when the whole procedure got cancelled just b4 dispatching appointment letters to selected ones....i myself was a victim of it after passing with 75 marks n also qualifying the Gd n interview phase....
