I really like this sort of question since it allows a candidate to work their own way while showing their process and lets the company see if the applicant can handle the sort of thing that will be a good part of their job, at least for the first year or so. The popularity of white boards and writing binary tree traversal pseudo code is frustrating to me. I haven't done an interview where that's a part of it because the thought of it freaks my brain out a bit. Which seems odd since I regularly perform improv comedy and am considering teaching it in the near future.
