A persons profession might actually be what the person Want's to be good at.
During my time in Nokia I witnessed how experience and competence were repeatedly ignored when organizations were reshaped according to new strategies. Further, when this was understood, there was a strict guidance to ensure that recruits had proper education, which led to overlook the experience.
People really can make up their experience or credibility and talk themselves into almost any job and learn while doing, like the fake doctors also have shown. Fact is that a person might turn out to be incompetent despite the long list of experiences, but on the other hand person can be extremely skilled, but totally lack the motivation for the job.
Despite the idea of crafting ones career might sound awkward for Finnish ears it should be considered. It is proven to be a clear weakness in the competition between Finnish and foreign applicants e.g. in Nokia and has lead to less competent people doing the work with better accent.
Developing a new career without years of training sounds unorthodox for some, but it can be seen also as a huge possibility. This thinking does not corner people into their slots, but opens new possibilities, keeps the motivation up and creates cross discipline innovations.
What really matters, is whether a person wants to learn and grow to a new profession and from employer point of view, is the person interested in the right aspects of the role with potential to learn.
