My company actually encourages the use of AI. My interview process was one relatively complex take home, an explanation of my solutions and thinking, then a live "onsite" (via zoom) where I had to code in front of a senior engineer while thinking aloud.
If I was incompetent, I could've shoved the problem into o1 on ChatGPT and probably solved the problems, but I wouldn't have been able to provide insight into why I made the design choices I made and how I optimized my solutions, and that would've ultimately gotten me thrown out of the candidate pool.
Just a new term used during and after COVID. It comes after the initial 'tech screen' round. They call is 'virtual onsite' sometimes. It involves giving multiple interviews in a very short duration. A positive decision in these 2-3 rounds pushes you forward to the final round with the hiring manager.
