Heh, well done. (And much more concise than mine.)
Mine was something like (also paraphrased) you can't be serious, reference to rodents in a maze, incredulous chuckle, sorry you have to be there, no thank you, kthxbye.
It really rubbed me the wrong way. Even as a teenager interviewing for Starbucks in a group setting for a minimum wage job that started at 3am every day, they treated everyone with more humanity and respect. I don't know how this company manages to hire anyone at all. Maybe they're specifically filtering for compliant minions who never question authority. Shrug.
