Office Hours is a new podcast that has been launched by Zillow Group CEO, Spencer Rascoff. He oversees the company’s portfolio of real estate and home-related brands, including Zillow, Trulia, StreetEasy, HotPads, and Naked Apartments. Episode 1 features the very first guest of Office Hours, Entrepreneur and former CEO of Twitter, Dick Costolo.

In the first episode, Spencer Rascoff and Dick Costolo discuss leadership tips and secrets. Dick Costolo taught a management class at Twitter.

In the episode, Dick Costolo says the key to being a successful leader is “listen, decide, then communicate” (which should not be confused with “decide, listen, communicate”). The first episode of Office Hours has been released on Zillow’s website and on iTunes, where it will be released monthly.

Upcoming episodes will include:

* Citigroup CEO Michael Corbat

* Ellevest CEO Sallie Krawcheck

* Mod Pizza CEO Scott Svenson

* Trello Co-Founder Joel Spolsky

Office Hours was introduced with a question: “When a couple of CEOs get in a room together, what do they talk about?” The podcast lets you listen in as Spencer Rascoff “has the kinds of conversations that can only happen when peers get real: tackling tough questions, sharing hard-won insights, defining what leadership means in the digital age.”
