I graduated with 2:2 elect/elect engr in 2009,i finished my nysc june last year,i ve been hoping for a very good job but none in sight,i recently had an appointment offer with nigeria civil defence on school cert level, GL 03 with a salary of N40,000.pls advice me on this,should i accept or reject this?pls with reasons.

Do you have other employment offers? If no accept it. In these kind of military parastatals, you get promoted gradually and your salary gets reviewed almost anually Tho i feel GL 3 is too low for a graduate. Its better to start from somewhere. If you don't like it, be on the lookout for another one but DO NOT leave your current employment.
i suggest you get some military training (if you haven't) to give you the upper hand. Good luck.

Thanks dominique,its highly appreciated

You welcome
just bear in mind that Rome was not built in a day. I know of people who started out on the lowest level with modest income, now they hold directorial positions with comfortable six-figure income. Though it took years to achieve this, but it paid off eventually. Its all about hardwork and dedication.
have you read the conditions of employment?
