I really enjoyed this Hillel Wayne post: "Many Hard Leetcode Problems are Easy Constraint Problems" -- it's never occurred to me to use a constraint solver to solve coding interview problems, but this would be way nicer than coding up some dumb algorithm from scratch.

Also I refuse to ever do another coding interview ever again, so this information is mostly useless to me at this point. But I'd love to know if anybody else has tried it!
