I love your list. Full of great ideas for productive interviewing. I'd further expand this one: - Write the problem down ahead of time. Have someone else at your company read it. You also need to have someone else (not you) at the company complete the problem. Ideally have a "model employee" do it. If they are unable to "pass" your interview question (under near-interview conditions) then maybe the question is a bad indicator. Keep in mind that asking a co-worker to complete it is much lower stress/easier for them than a candidate, as they likely have near nothing on the line (maybe reputation). So if they find it hard, an interviewee will likely find it near impossible.
