When hiring somebody one posts a job description with the desired technical skills.
Most of the time the technical skills have little relevancey. Especially in IT things change so fast that it’s not important what one knows today but how willing that person is to evolve, learn and contribute to the job.
What would motivate somebody to do so?
Answer: company culture. If he / she is a good fit for the company, then there will be chemistry, there will be love, passion and the desire to contribute. With the Internet at your fingertips you can learn so many things if you’re willing to.
