If a person can use AI to complete an interview task, why don't you think they'd be able to use it to complete a work task? I think this thinking is flawed. 15 years ago the argument was, "they'll just use StackOverflow during their take home test." But then once we all got the job we'd check StackOverflow to help solve problems we come across. I don't think AI should be treated any differently, it's a tool to complete the job.
