Are you explaining this to the interviewee. Otherwise it's a guessing game for what you want and creates unnecessary stress. If you planning to put people on-call (working under stress and time constraint) on their first day(no prior knowledge of the problem they may encounter) then its fine. While I'm a decent programer, I perform terrible under these situations. When I get stuck I need to take two steps back (go for a walk, explain it to a coworker/rubber duck).
