Job Interview Candidates - Bringing Notes Into Interviews

We've talked about coffee in job interviews, but what are people's thoughts on candidates bringing notes into interviews? A heated debate has kicked off on Mumsnet, and many people have claimed it's 'unprofessional' and a 'mistake' to do this. Do you agree? Would you have an issue with someone bringing notes/prompt cards into a job interview? I'm looking to hear people's thoughts for Metro.co.uk 📝
