The software industry has a strange practice of seeking employees who have a certain number of years experience with a particular technology. A job posting might require "at least 5 years experience with Java" or something like that. At first glance, this might seem reasonable, but it is actually kind of weird. It is easily possible to continue to do something badly for a very long time, so that adding more years will not add any more value.
For example, I know people with over 5 years experience using a VCR who still cannot set the clock. But they can press play, stop, fast forward, and eject, and that is all that matters to them. I think that even after 10 years experience, these people will still not be able to set the clock.
So I do not want to work on a team with someone with X years of experience with a technology. I want someone with X units of skill with a technology, and the more rapidly they acquired that skill, the better. Of course, skill is harder to measure, which is why the industry falls back on years of experience.
