Hi, I once got a job out of a skype interview (zoom wasn't even thought of then). I remember the experience vividly.
What I found most stressful was that it was impossible to judge the mood in the room from the little blobs that people's faces were on my laptop screen. In my profession (academic, so a bit waffly) I'd normally take physical cues from the person who's asked a question in discussion to know when I've said enough - the way they nod, make eye contact, etc. I realized within the first minute of this interview that this wasn't going to work on my screen.
The skype interview was more like performing to an audience - you have to say your say and not worry how it comes across, if it falls flat it falls flat and you don't even know. Of course it may be a bit better with the little boxed-in individual faces that you get on zoom - but then, in that scenario everyone is atomized and you still can't judge the overall mood. There may not even be one if people are dialing in from separate offices.
It may help you to practice in front of an empty chair, or with a friend who asks questions but, say, stands behind you.
It never even occurred to me to use post-it notes...
Btw. I doubt I would have got the job if I'd interviewed in person - it was in a social setting (Cambridge University) that I find uncomfortable. So the online set-up got me a very fancy job. Except it was so uncomfortable that I left again.
