You can easily add videos and other embedded media to job listings. All you have to do is get the URL to the video (i.e. YouTube, Vimeo) and paste it into the editor.
This will work for most major content providers, including video sites like YouTube and Vimeo but also Google Maps, Slideshare, Twitter, and many others.
The embedded videos are mobile-friendly so they will show well on mobile devices as well.
