Here's how you can change a job's status according to your need.
You can only have a certain number of jobs in the active slots. You can see the allowed number of jobs and number of currently active jobs from the 'View All Jobs' button in the sidebar.
In order to increase the number of allowed active jobs for your organisation consider upgrading your subscription. For more details check the 'Billing & Payment' section: www.hirecinch.com/catogories/billing-and-payments
