Let's examine the three characteristics you used to describe the value of older workers. You probably know more than a young job-seeker does. But your knowledge has to be relevant to the job, and during the job interview you have to present effectively what you know. Describe outside learning activities you are currently engaged in. If you have often enrolled in a course or seminar on your own time and used your own money, be sure to mention that.
Past performance is a good predictor of future behavior.
The closer you are to retirement age, the more important it is to stress your interest in continuing to learn. Employers need to be convinced that you will follow through on that promise. But experience alone does not get a person hired. You need to understand the type of experience a prospective employer needs to help the organization run well. Describe examples of problems you solved and projects you successfully completed that relate to the job you are applying for.
