I want to how department name

Hi there!

By default, we do not have such a feature available. You could use the ‘category’ option for your ‘department’ information, then use shortcodes to display this: https://wpjobmanager.com/document/advanced-usage/shortcode-reference/

If that does not meet your requirements or you need assistance implementing this, it would be best to hire a developer to assist with making the necessary customizations. You can also submit a feature request for it here.
