Only a human being would be able to assess whether candidates are capable, personality-wise, of sharing and disseminating that institutional knowledge to help other newer and younger workers.

I think what's happening is companies are trying to maximize shareholder value and I think they realized that if they could hire more effectively, they would. What I'm suggesting, though, is that human resources departments in most companies have become so detached - have become such a bureaucracy - that they have become clueless. They don't realize that the processes they have put in place have very little to do with recruiting, retaining and bringing on talent.

An online job search seems cheaper. But what HR is doing is turning away valuable candidates. They're experiencing false negatives. That means the right person applies for the job electronically but the algorithm kicks them out so they lose that individual.

On a strategic level, employers really are behaving stupidly. Look at how they do recruiting: this automated process under which they will publish a job description chock full of so-called "key words", and then have software algorithms that attempt to match applicants to the resumes against those key words. So where in the key word collection do we capture institutional knowledge? No one advertises for that. Of course they don't.

When you're not recruiting effectively you're not recruiting properly through a certain channel, like a job board, then what's left of you? I don't believe HR's been able to figure that out. They need to go back to the way they used to do it. They complained that they got so many millions of applicants, they couldn't possibly spend the amount of human time on all those applicants. But they could solve the problem tomorrow if they stopped soliciting millions of applicants through job boards.

I really don't think that an older worker can stop age discrimination, but you can successfully distract the employer from that issue if you focus on the reason they really want to hire you and that can make you more successful. It's up to you to demonstrate that.

Remember, the word "discrimination" isn't always pejorative. When an employer discriminates because an older worker lacks certain kinds of skills that are important in the market today, then it's almost a legitimate form of discrimination because the employer is just trying to figure out who can actually get the job done.
