It depends- maybe if people devoted enough time to cramming algorithmic problems (more than they did in their CS classes, even) could they have memorized enough solutions and seen the patterns enough to be able to master this type of technical interview? One wonders, can that rote memorization + pattern machine process be trained into anyone- meaning that this is not a measure of intelligence but of brute force, like memorizing Rubik's Cube solutions?

And then the practical concern arises- does that actually make anyone a better programmer, and benefit employers?
