In my case, the question was "how are you using AI tools?" And trying to see whether you're still in the metaphorical stone age of copy-pasting code into chatgpt.com or making use of (at the time modern) agentic workflows. Not sure how good of an idea this is, but at least it was a question that popped up after passing technical interviews. I want to believe the purpose of this question was to gauge whether applicants were keeping up with dev tooling or potentially stagnating.
