I have been quite known to ask weird questions to potential team members.
Some of my interview questions for junior or mid-level positions in a media/comms planning role include things about outer space ("how many planets are there do you think?"), ET ("do you think there's intelligent life out there or are we just wasting our time and money looking for it?"), and the more-technical stuff ("how would you explain to me linear regression if I were a 12 year old boy?", "what's degrees of freedom in stat testing?", "what's the probability of rain tomorrow, do you think?")
I have never asked "what are you into?"
Maybe, I should start asking that question.
(Or at least some semblance of it - I don't want to be sued for harassment or discrimination! hee)
