What happens once you start a Google+ Hangout
Well, the first thing is that you are asked to add circles and friends to your hangout. Since hangout out alone on a video chat is no fun. Once you have friends whoa re also online they will appear on your chatroom after you adding them. Your friends will also know you are online and can drop by unexpectadly to say hello. All this happens face to face in real-time and excellent clarity. It seems as though everyone is in the same room although maybe separated by continents. 

Once you start a hangout you can check your video, audio and microphone settings by clicking on the settings icon. If you are bored and waiting for people to join you, you can also watch some YouTube videos right inside your hangout window. 

How to join a Hangout

There are plenty of ways to find out who’s hanging out. And, joining a hangout that's already going on is easy.

You can check out your stream or the green room to find out if people in your circles are hanging out. If you see a group of people that you’d like to hang out with just click the Join this Hangout button.
Your friends may also send you the URL to a hangout in which case you can copy and paste the URL into your browser or simply click the URL link.
Since no one likes hanging out alone, it’s likely that when someone starts a hangout, they may select a group to notify. If you are in this group, you'll get notified at the top of the page. If you've been individually added to the hangout and you can chat with the person, you'll get a chat notification. (To avoid unwanted notifications, we don't notify circles with a large number of members).
When you enter a hangout, you'll see the current participants, broken down according to who is in your circles and who isn't. This way you don't have to hang out with anyone you don't like, or don't know.

Who can see you if you are hanging out

Visibility of your hangout
There are a few different ways people can discover that you're hanging out:
If you invite people to join a hangout, a post will appear in their stream telling them that there's a hangout going on, along with all the people in that hangout currently.
If 25 or fewer people are invited, they'll receive a notification that they've been invited to join a hangout.
If you invite individuals that are signed in to chat, they'll receive an IM with a link to join.
If someone invited to a hangout tries to start their own, they'll be told that there's a hangout already going on and they may want to join that one instead.
Since the hangout you're in is visible by the circles of the other hangout participants, people you don't know may learn that you're hanging out.

You can also Text chat in Google plus hangouts, this is in case you are making too much of a noise or maybe you are tired of talking and want to go the good old fashion way of just text chatting.
