Qualification
This so subjective.the assumption is that you have optimized your skills match and established demand by showing demonstrable skills the buyer wants.The truth of the matter is this advice only applies to a small section of the workforce.Many job seekers will take a job where there is no skills match for economic reasons or seek to gain new skills as market demand for skills in the market changes.Clearly within companies my research produces only 30 % optimization of skills in the workforce creating such a demand curve.So be careful about such wide briefs!!
Best advice is to do your homework on the employer,realistic market value of your skills,move to a position of specific skills or specific buyers match to potential employers to create value.
However money is one building block of doing a job?
