What to Bring

Additional Information

On December 5, Netflix and Warner Bros. Discovery announced they have entered into a definitive agreement under which Netflix will acquire Warner Bros., including its film and television studios, HBO Max and HBO. The transaction is expected to close after the separation of Warner Bros. Discovery's Global Networks division, Discovery Global, into a new publicly-traded company, which is expected to be completed in Q3 2026. For more details, including leadership appointments and information on individual brands, please visit our newsroom here.

Although you will be hired by Warner Bros. Discovery, upon the planned spin-off of Discovery Global in 2026, your employment likely will transition to Warner Bros. During this period of transformation, you'll have an exciting opportunity to lay the foundation at one of the world's premier entertainment brands.

This last bit is probably the most important! Here at WBD, our guiding principles are the core values by which we operate and are central to how we get things done. You can find them at www.wbd.com / guiding-principles / along with some insights from the team on what they mean and how they show up in their day to day. We hope they resonate with you and look forward to discussing them during your interview.
