When we look at a job advertisement, it can seem as though employers want an exhaustive list of experience and technical persons from their new hire. Those words can mean a variety of things to different people and it can be quite hard for employers to illustrate fully the combination of technical and soft skills they want their versatile employees to have. What they often want is a mix of versatile skills that make it easy for them and you to adapt to the changing needs and demands which occur in businesses today.
Sometimes unpredictability is a good thing — such as when great opportunities emerge out of the versatile and you want to make the most of them. And it can be associated with adverse circumstances that affect your job; for example an organisational downsizing. Another example of circumstances that can be hard to predict is when professionals choose a career direction that persons out to be wrong for them.
