JAG 3
Regardless of country or profession I have noticed that the best vacancies are seldom ‘advertised’.
Some employers - especially if they have only one or two very special slots to fill and have no need for continuous recruitment - may use headhunters to produce a high quality short list on their behalf.
Others – such as the RAF – have quite a few annual slots to fill but are faced with many more really high quality applicants than they can possibly need. In such a situation they spend their money on developing the best possible assessment programmes.
Sorry if common sense pisses you off.
