Maybe I don't know enough but I believe having any person talk about a few random projects from their CV and me asking them questions relevant to their position would give me a pretty good understanding of how much someone is knowledgeable in their field, as well as their confidence and general curiosity (it's ok if they just know their bit but plus points if they can also talk about design, business and/or other parts outside of their role.) Of course one could learn that by heart and fool me but I'm also pretty sure people are currently wasting/spending their time memorising acronyms and leetcode just to get someone to give them a chance, so I'd rather have both enjoy the process.
