It's 100% true. Some that did the interview were part of 2010 NNPC recruitment and that category (which I belong) did not write the aptitude test. They were only invited for the interview. A day before my interview was scheduled to take place I visited NNPC retail office to iron out some issues before my interview the next day and to my surprise I was stopped at the gate and was told i could not enter as there were people writing test inside. I waited until after the test and was allowed in. We did interview with these same guys the next day and they confirmed they were never part of the original 2010 NNPC recruitment. I discovered all of them had some top shots backing their candidacy. I figured out that the main reason we were called at all was to give the exercise some measure of credibility but the main target was these guys. From that day I started praying hard because we could end up being thrown out after the purpose of inviting us must have been served. I am just hoping that I am among the favoured even without any oga because my immortal OGA is at the very very top.
