Please I want to know why most people posting job positions find it hard to include the job location in their post, or don't the know that nigeria is a large country and most people can't afford to travel from one state to another to attend an interview that you are not even sure the will employ you. Please let's learn to always include job location in our post it will help so that you don't get so many applicants that may end up not coming for an interview when invited

Run away from such adverts. A credible job advert should include the name of the company. Even most consulting firms who recruit on behalf of some companies do include the name of such companies they are recruiting for.
