I have to say I'm (half) amused by the very low adequacy between the job offers I receive through LinkedIn and my actual profile.
I found the mismatch ridiculous, most of the time.
When I get offered junior industrial automation programmer positions, while being in charge of the European OT and automation program for a major Global company for 8 years now, and with 36 years experience in leading teams, there is kind of a "disconnection"
I find that funny because I'm not looking for another job. But if I was, I'd find that infuriating, for sure.
On the other side, I see a huge difference between "cheap" consultants that people teams are using to find and hire profiles we're looking for - most of those consultants are just using some more or less advanced search tools, while having no experience and zero understanding what the words actually mean - and, at the opposite side, clever companies that, on the contrary, bring the right experts on board to tune the search and filter results, understanding exactly what we're looking for.
Not surprisingly, the former are a pure waste of time, while the later always find quickly what you're looking for. And then charge a crazy fee on every hour you pay for.
