The hardest workers with the most successful can-do attitudes will simply reject your company if you ask them to do bullshit like algorithm trivia or HackerRank tests.<p>Such trivia is the opposite of useful hard work; preparation for it truly wastes time that could be better spent on other things; a can-do attitude would imply rejecting or ignoring requests to do such things.<p>As a result, the people who actually do take the time to complete it will not be completing it because of a good attitude or work ethic, yet you will mistakenly believe they are.
