Check out the Dahlem Research School's podcast! They also offer workshops based on the episodes:

The Dahlem Research School podcast for prospective and current doctoral researchers was created to help support individuals who are considering a doctorate or who are already working on a doctorate. Across various seasons of the podcast, you’ll hear from former and current researchers talking about their experiences with the doctorate and in their transition to the job market after completing their doctorate as well as from various experts at the Freie Universität and beyond. We hope this podcast will help support you in successfully navigating the challenging and exciting doctoral process.
After the release of an episode, short workshops will be offered where the topic can be discussed in more depth or experts will be invited to answer your questions.
