An &quot;optimal&quot; amount of time? So we expect &quot;good enough&quot; solutions to be materialized in a matter of an hour?<p>If my PM ever walked up to me and said, &quot;Hey, I have this project, and I need you to have it back to me in an hour,&quot; I would laugh, then escort them over to their boss, who would also laugh at them before they walked back to their desk in shame.<p>It&#x27;s not testing anything but whether or not you&#x27;re good at studying for exams.
