When you create a position in your account, it will be assigned a unique URL address. This address can be found directly below the job title. You can access the job title page from your dashboard by clicking on Dashboard and then clicking on the job title in the Active Jobs section of the page.
From there, you will see a unique URL located just below the job title. See below for an example of a unique job URL.
You can copy this link and insert it into any job board outside of the network to get additional exposure to your job, and have all of applicants stored info, regardless of where they came from.
