If it was a while ago things might have been different. Not sure if you are around anymore but there is a continuous push for standardization. There is also a big emphasis on candidate experience lately.
I also believe in adding a personal touch to the interview process, but I don't believe in mind games. To me this would fall in the same bucket as "let me mispronounce your name on purpose and see how you react" or "let's give the candidate the wrong directions and let them figure out the way". You could frame it the other way around, what if it goes wrong? at best you lose some valuable interview time and annoy the candidate, and doesn't tell you much about how good they will be at the job.
