This may not be a best talk and nor is the speaker any more eloquent than a few other speakers at TED but this topic has some big value and hence this is listed under a few of my favorite TED talks. The speaker, Celeste Headlee worked as a radio host and writer and here she discusses some of the 10 rules to get back to this lost art of having conversations. The ones shared by her are a few of the important things to remember while conducting interviews (my PhD classes). Do watch it to learn more about how to have a good conversation.
By the way, this was filmed in May 2015.
