HR person surprised me when asking if I had my presentation ready when she took me to the interview room. I asked her what she was talking about, and she said her email had advised me that I'd need to create and present an catman example to my interviewers, and that I was supposed to have hard copies for them. (I subsequently checked my emails, and confirmed that there was no mention of a presentation). After the interviews, she told me that she double checked her records, and that this position did not require a presentation.
