The term ‘job description’ is a flexible one, but here I’ll be using it in a modern context, to describe all of the copy you’d use on an online job board. It usually includes information like job title, duties, salary, etc.
Write a description of your company or organization. This overview will be included with all job descriptions, to give a sense of your workplace. Thus, it can be written ahead of time so that it can be inserted into the template when you prepare it.
