You’re the host. You decide what’s necessary for your podcast.
If you want a pre-interview, get it.
If you need guests to wear headphones on remote sessions, because you don’t want to edit the echo of your own voice coming back into their mic from external speakers, make them wear headphones.
Same for guests connecting to remote sessions from quiet places. And using quality mics that don’t make them sound like somebody at a Taco Bell drive-thru.
Need to take more time to properly edit an interview? Do it, even if you miss their important launch date.
“Guest deadlines” don’t become your deadlines.
Yes, it’s good to work with people and be flexible at times. But don’t do it at the expense of your listeners.
Do whatever you need to produce the podcast your listeners deserve. It’s that attention to quality that made guests case about being on your podcast in the first place.
So if you need a pre-interview, get it.
You are in charge of your podcast.
