Chat Rooms are places where you "meet with" other people, online, at the same time, and talk with each other using your keyboards. It's like watching the dialogue from a play script unfold line by line on your screen. Along with the sites listed, many job boards and job sites have chat rooms, though these are often more useful for venting your frustrations than finding people with the power to hire you.

Generally, chat sessions are between a number of people: most sites allow any number of people to "listen", but may have limits to the number of people who can get in at any moment to "talk". Some of these will be moderated, meaning that there is someone in charge, watching over the conversation, with the power to disconnect those who behave badly, but in fact these are rare, and most sites require self-policing. Many sites allow you to search through past conversations by keyword, so be careful what you say; it may be stored somewhere for a very, very long time. Some chat sites will allow you to leave the main thread, and "go off" to a private room for one-to-one conversations, but these are usually sites that lean towards personal relationships, rather than business ones. In fact, of all of the ways you can meet, and communicate with people, chat rooms are the least likely to be useful in your job hunt.
