Once you get to the interview process, it's very clear if someone thinks they can use AI to help with the interview process. I'm not going to sit here while you type my question into OpenAI and try to BS a meaningful response to my question 30 seconds later.
AI-proof interviewing is easy if you know what you're talking about. Look at the candidates resume and ask them to describe some of their past projects. If they can have a meaningful conversation without delays, you can probably trust their resume. It's easy to spot BS whether AI is behind it or not.
