Job Titles are meaningless. Except they aren't. We focus too much on them and they say nothing. There used to be the joke that you couldn't swing a stick in a bank without hitting a VP. They gave titles out that made no sense.
Worse, they don't tell you what people do. Yet we rely on them so heavily. Recruiters look at titles to see fit for roles. Employees see titles as recognition they deserve. Companies see titles as a way to define responsibility (except they don't really use them that way).
I even find myself struggling with them. I see someone's LI profile and it says "helping people succeed in marketing" and I wonder what the job title really is.
We need to figure out how to get past that. I don't have the answer, but it will be an issue.
