Did I Actually Sneak In?

A firm(telecoms) wanted the services of a youth corper and few people were conacted to go for an interview which I also attended.I was finally picked as the best amongst the lot that attended the interview.

The truth of the matter is that I wasn't a corper(I graduated 5 years ago and served same year)

The regional manager later got to know that "I snaeked into the company"and wasnt happy with either me or my manager(my manager wasnt even aware of this move).

It has now come for me to be confirmed as a permanent staff,but this issue stated above is what I have to contend with.Did I make a wrong move considering the fact that jobs(good jobs) are not easy to come by in Nigeria?
