Yeah, the disclosure is very important. It’s the difference between an open book test and notes written on their thigh.
During some interviews I’d give people access to a computer. If they could quickly find answers and solve problems, that is a skill in itself, but I could see what they were looking up. Sometimes that part would make or break the interview. Some people didn’t have a deep base of knowledge in the area we were hiring for, but they were really good at finding answers, following directions, and implementing them successfully. They would be easy to train on the specifics of the job. Other people couldn’t Google their way out of a paper bag, I was shocked at how bad some people were and looking up basic things. Others simply quit without even attempting to look things up.
