International agencies
In our country there are lots of donor agencies and international NGOs which are working in different areas. To conduct their business they give advertisements for filling up various positions, but most of the time they have their own people for those positions. They avoid violation of rules through giving those advertisements. Sometimes they call the candidates for interview. But that is really immaterial.
People are wasting time and money and dreaming of getting a job with an international organisation. The issue deserves a closer look.
