Privacy invasions aside, they don't even have an industry category for EE's or R&D, just Civil and MecE's.
This is most frustrating thing about linkedin, or any recruiter basically. They don't understand their market!
Because no matter how you setup the notifications,
they will keep emailing you.I'm an Embedded Software Engineer, which means I do basic electronics, and software for devices.
If I put: "Industrial Automation", I will get job offers and recruiters looking for IoT Security advisors and PLC programmers. I'm not one of those.
If I put: IT or computer -anything, I will get job offers and recruiters looking for Java/C# or web developers. Never.
If I put: "Consumer electronics", I will get job offers and recruiters looking for sales people.
So I just put "semiconductors industry", since those people don't recruit much, and when they do, they search for test engineers or project managers and anyone with an electronics background.
