Starting now, you have the ability to use Hangouts from Google Calendar!
Now it's easier than ever to schedule a face-to-face interview with a candidate located hundreds of miles away or plan a date to catch up with your buddies.  To do so, make sure you've upgraded to Google+, and then you can add a hangout to any calendar event with one click. Everyone you invited will be able to join by clicking on the calendar event and selecting Join Google+ hangout.
