Let them use their preferred setup and AI to the full extent they want, and evaluate their output and their methodology. Ask questions of "why did you choose X over Y", especially if you're skeptical, and see their reasoning. Ask what they'd do next with more time.
It's clear when a candidate can build an entire working product, end-to-end, in <1 day vs. someone who struggles to create a bug-free MVP and would take a week for the product.
In addition to the technical interview, hiring them on a trial basis is the absolute best if possible.
Taste and technical understanding of goals and implementation to reach those goals is the biggest differentiator now. AI can handle all the code and syntax, but it's not great at architecture yet - it defaults to what's mid if not otherwise instructed.
I do feel like there's something *different* about the required skillset now, and it's not something that all engineers have even experienced ones. But I can't put my finger on what exactly it is. If I'm right though, classic interview techniques won't select for it because they never were intended to do so.
Either the machines exterminate us or we become glorified pets.
Hope the AIs prefer us to cats (even though that's a long shot).
