Coding interviews are nothing like your day-to-day. I don't know about you, but I can't think of a time when I had to find how may different ways I could make a 7 out of a list of numbers. Doing these well is a skill and since these tests aren't going away, this skill needs practice. I signed up for a mailing list that sent me one question per day. We'll work through some of them together.
Please bring a laptop. If attendance approaches the max, we may split up into groups to work on a few problems.
