I've attached data extract project and sample data extract.
It can be very difficult to extract data from Linkedin, and there's a limit to what we can do in a demo project.
In the attached demo project you'll need to add values for email and password to login (I've created the data extract with my own login, which I've deleted from the project, so you'll need to add your own).
The demo project uses a fixed company name "General Motors" which you can change manually in the project. If you want to be able to run a project for a list of companies, it becomes more difficult and we cannot do this in a free demo project.
