How to Post a Job Listing on LinkedIn
Using the text boxes and lists provided, enter the required information about your company and the job you're offering.
When it comes to your company, LinkedIn asks for your company name, a description, and the industry your company represents. As for the job posting itself, you need to specify the job title, employment type, experience level, and function.
When you're done with that, you can scroll down and compose your job description and desired skills and expertise in the text boxes provided or copy the description from another source and paste it into the box. Just make sure any formatting (spacing, bullet points, font size, and so on) is correct after you paste the text.
If your company isn't that well known, you should include some details about the company in the Company Description field. If the job title seems a bit ambiguous, you can elaborate a bit by filling out the skills required for the job title in the Desired Skills and Expertise field. LinkedIn recommends adding at least one skill to the job posting.
