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.

There is age discrimination, but I think there are two kinds. One is when the employer is discriminating for specific reasons and doing it intentionally. The other is where you have managers who really aren't looking to discriminate but feel a little on edge because the candidate they're talking to is older. Sometimes they can even smell age concern on the part of the candidate and they wind up discriminating almost unconsciously.

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.

Companies are missing out on phenomenal skills and capabilities of experienced older job hunters: wealth of knowledge, expertise, seasoning, maturity. Companies need to be reminded of 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.

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.

The most successful people are those who are wildly enthusiastic about their work.
