If you’re inviting guests to your podcast, you can use Calendly to let them book a slot with you.

Here are some questions (just examples, you can modify as per your needs) you can ask them prior to them coming to your show for a smooth recording:

What do they want to share with your audience?

Will they follow a script or have a candid conversation?

Do they want to keep some topics out of the conversation?

What do they want to highlight?
