This is exactly it. One of the guys we interviewed failed because he used AI. The AI gave him a stack which made it difficult to complete the task in the given time. Well, that was the story anyway. Some team members were already using AI for production code and pointed out that if he had knowledge of the good stack, he would have just asked AI to build the good stack instead of relying on it to build the whatever stack. For context, the senior interviews we give don't force tool or stack. They're problems we have trouble with. The aim is to find someone smarter than us who brings in a new tool or stack which solves this problem better. If we wanted to test promises skill, we'd give a complex async problem, like getting them to clone the box in Facebook with emoji count and stuff.
