On this site I see many answers and comments that say it is easy to find another job. Yet I have read statistics that say that 6 months is reasonable, and perhaps much longer. My brother, an experienced developer and manager of developers, looked for 2 years recently.
I also see job listings go unfilled for many months, and reappear over and over under different recruiting companies' names. I think some of these positions are still unfilled after a year. And I am in one of "Forbes best places to live".
For some strange reason, this process is not easy for either side, and I thought that computers should have made it basically an instant, push-button match-up. (Don't get me started on the effectiveness of dating sites.)
What accounts for the persistent advice that changing jobs, or employees, is basically trivial?
