You have nothing to fear. Try to go with all the originals of your credentials most especially, your first School leaving certificate and Birth Certificate/baptismal Certificate, declaration of age will not be accepted. First go to the Imo State Civil Service commission and fill your Bio-Data after which you will go home and prepare for the interview, just be conversant will your field and also pray that you will not be among the first set to be interviewed cos the set will answer lots of questions because the interviewers use to be strong at the beginning but after three sets, they tend to be weak and like to finish on time, all the same, best of luck. You can call 08061651960 for further clearification cos i have done mine and i am residing in Imo State.
