I think this is an extremely interesting interface. Not only for journalist interviews but for personal brand sites.

Take a look at Adrian Zumbrunnen's personal site: https://azumbrunnen.me/

(Unfortunately their SSL cert has expired so you have to click "Proceed Anyway")

It's an embedded chat with Adrian.

I feel like it's an equally valid experience vs. reading their CV and recent projects. By clicking through the chat I not only learn about the site author's expertise but also learn a bit about their personality.

I know I'm not really chatting with them but it still feels more personal and human.
